doc: remove OSS-vs-Ent Matrix from OSS 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.

Fixes https://github.com/scylladb/scylladb/issues/17289

Closes scylladb/scylladb#17295
