This PR adds the upgrade guide from version 2025.2 to 2025.3.
Also, it removes the upgrade guide existing for the previous version
that is irrelevant in 2025.2 (upgrade from 2025.1 to 2025.2).
Note that the new guide does not include the "Enable Consistent Topology Updates" page and note,
as users upgrading to 2025.3 have consistent topology updates already enabled.

This commit adds the upgrade guide from version 2025.1 to 2025.2.
Also, it removes the upgrade guides existing for the previous version

This commit fixes the product names in the upgrade 2025.1 guides so that:
- 6.2 is preceded with "ScyllaDB Open Source"
- 2024.x is preceded with "ScyllaDB Enterprise"
- 2025.1 is preceded with "ScyllaDB"

This commit adds the upgrade guides relevant in version 2025.1:
- From 6.2 to 2025.1
- From 2024.x to 2025.1
It also removes the upgrade guides that are not relevant in 2025.1 source available:
- Open Source upgrade guides
- From Open Source to Enterprise upgrade guides
- Links to the Enterprise upgrade guides
Also, as part of this PR, the remaining relevant content has been moved to
the new About Upgrade page.
WHAT NEEDS TO BE REVIEWED
- Review the instructions in the 6.2-to-2025.1 guide
- Review the instructions in the 2024.x-to-2025.1 guide
- Verify that there are no references to Open Source and Enterprise.
The scope of this PR does not have to include metrics - the info can be added
in a follow-up PR.

This commit removes the information about the recommended way of upgrading
ScyllaDB images - by updating ScyllaDB and OS packages in one step. This upgrade
procedure is not supported (it was implemented, but then reverted).

for following reasons:
1. the ppa in question does not provide the build for the latest ubuntu's LTS release. it only builds for trusty, xenial, bionic and jammy. according to https://wiki.ubuntu.com/Releases, the latest LTS release is ubuntu noble at the time of writing.
2. the ppa in question does not provide the packages used in production. it does provides the package for *building* scylla
3. after we introduced the relocatable package, there is no need to provide extra user space dependencies apart from scylla packages.
so, in this change, we remove all references to enabling the Scylla/PPA repository.

This commit replaces the 6.0-to-6.1 upgrade guide with the 6.1-to-6.2 upgrade guide.
The new guide is a template that covers the basic procedure.
If any 6.2-specific updates are required, they will have to be added along with development.

This commit removes the 5.4-to-6.0 upgrade guide and all references to it.
It mainly removes references to the Enable Consistent Topology Updates page,
which was added as enabling the feature was optional.
In rare cases, when a reference to that page is necessary,
the internal link is replaced with an external link to version 6.0.
Especially the Handling Cluster Membership Change Failures page was modified
for troubleshooting purposes rather than removed.
This commit adds the 6.0-to-6.1 upgrade guide.
Compared to the previous upgrade guide:
- Added the "Ensure Consistent Topology Changes Are Enabled" prerequisite.
- Removed the "After Upgrading Every Node" section. Both Raft-based schema changes and topology updates
are mandatory in 6.1 and don't require any user action after upgrading to 6.1.
- Removed the "Validate Raft Setup" section. Raft was enabled in all 6.0 clusters (for schema management),
so now there's no scenario that would require the user to follow the validation procedure.
upgrade/_common are document fragments included by other documents.
but quite a few the documents previously including these fragments
were removed. but we didn't remove these fragments along with them.
in this change, we drop them.

This commit replaces the 5.4-to-5.5 upgrade guide with the 5.4-to-6.0 upgrade guide,
including the metrics update information.
The guide references the "Enable Consistent Topology Updates" document,
as enabling consistent topology updates is a new step when upgrading to version 6.0.
Also, a procedure for image upgrades has been added (as verified by @yaronkaikov).

This commit includes updates related to replacing system_auth with system_auth_v2.
- The keyspace name system_auth is renamed to system_auth_v2.
- The procedures are updated to account for system_auth_v2.
- No longer required system_auth RF changes are removed from procedures.
- The information is added that if the consistent topology updates feature
was not enabled upon upgrade from 5.4, there are limitations or additional
steps to do (depending on the procedure).
The files with that kind of information are to be found in _common folders
and included as needed.
- The upgrade guide has been updated to reflect system_auth_v2 and related impacts.

Document the manual upgrade procedure that is required to enable
consistent cluster management in clusters that were upgraded from an
older version to ScyllaDB Open Source 6.0. This instruction is placed in
previously placeholder "Enable Raft-based Topology" page which is a part
of the upgrade instructions to ScyllaDB Open Source 6.0.
Add references to the new description in the "Raft Consensus Algorithm
in ScyllaDB" document in relevant places.
Extend the "Handling Node Failures" document so that it mentions steps
required during recovery of a ScyllaDB cluster running version 6.0.

This commit adds a placeholder for the Enable Raft-based Topology page
in the 5.4-to-6.0 upgrade guide.
This page needs to be referenced from other pages in the docs.
This commit removes the Open Source vs. Enterprise matrix
from the Open Source documentation.
In addition, a redirection is added to prevent 404 in the OSS docs,
and to the removed page is replaced with a link to the same page
in the Enterprise docs.
This commit must be reverted enterprise.git, because
we want to keep the Matrix in the Enterprise docs.

This commit removes the 5.1-to-2022.2 upgrade

no longer support.
We should remove it while adding the 5.4-to-2024.1

This commit adds the upgrade guide from version
5.4 to 5.5.
Also, it removes all previous OSS guides not related
to version 5.5.
The guide includes the required Raft-related
information.
NOTE: The content of the guide must be further
verified closer to the release. I'm making
these updates now to avoid errors and warnings
related to outdated upgrade guides in other PRs,
and to include the Raft information.
