Putting this on multi-region for @rmloveland but also pinging @ericharmeling who has been documenting internal tables.

On the virtual tables reference docs side of things, I don't think we necessarily need to add any more docs than we already have in https://github.com/cockroachdb/docs/pull/8909/files#diff-bcda3effacbfa77b339e9d2198a4f7eec5482f6bc0a6ab06e08042b81f34acc2.

Closing this for now...
