Restore warning commit status (#27504)

Partial revert of https://github.com/go-gitea/gitea/pull/25839. This
commit status is used by a number of external integrations, so I think
we should not remove it (See
https://github.com/go-gitea/gitea/pull/25839#issuecomment-1729002077).
This is a rare case where an existing migration needed to be alterted to
avoid data loss.
