This commit adds the .. only:: opensource directive
to the Raft page to exclude the link to the 5.2-to-5.4
upgrade guide from the Enterprise documentation.
The Raft page belongs to both OSS and Enterprise
documentation sets, while the upgrade guide
is OSS-only. This causes documentation build
issues in the Enterprise repository, for example,
https://github.com/scylladb/scylla-enterprise/pull/3242.
As a rule, all OSS-only links should be provided
by using the .. only:: opensource directive.
This commit must be backported to branch-5.4
to prevent errors in the documentation for
ScyllaDB Enterprise 2024.1
(backport)
