Introduce `ms` -- a new sstable format version which
is a hybrid of Cassandra's `me` and `da`.
It is based on `me`, but with the index components
(Summary.db and Index.db) replaced with the index
components of `da` (Partitions.db and Rows.db).
As of this patch, the version is never chosen
anywhere for writing sstables yet. It is only introduced.
We will add it to unit tests in a later commit,
and expose it to users in yet later commit.
This commit adds the information about SStable version support in 2025.1
by replacing "2022.2" with "2022.2 and above".
In addition, this commit removes information about versions that are
no longer supported.
