This doesn't apply for auth-v2 as we improved data placement and
removed cassandra quirk which was setting different CL for some
default superuser involved operations.

Closesscylladb/scylladb#18860
Fixes https://github.com/scylladb/scylla-docs/issues/4028
The goal of this update is to discourage the use of
the default cassandra superuser in favor of a custom
super user - and explain why it's a good practice.
The scope of this commit:
- Adding a new page on creating a custom superuser.
The page collects and clarifies the information
about the cassandra superuser from other pages.
- Remove the (incomplete) information about
superuser from the Authorization and Authentication
pages, and add the link to the new page instead.
Additionaly, this update will result in better
searchability and ensures language clarity.
Closes#14829
