This commit adds a short paragraph to the Raft
page to explain how to enable consistent
topology updates with Raft - an experimental
feature in version 5.4.
The paragraph should satisfy the requirements
for version 5.4. The Raft page will be
rewritten in the next release when consistent
topology changes with Raft will be GA.
Fixes https://github.com/scylladb/scylladb/issues/15080
Requires backport to branch-5.4.
Closes scylladb/scylladb#16273
(cherry picked from commit 409e20e5ab)
