Enable Container Registry DB backups for Registry GA
## Short description
<!-- add a short summary of what is being proposed -->
The container registry meta db is not currently being considered for backup using the current backup and restore rake tasks
https://gitlab.com/gitlab-org/gitlab/-/issues/532507
This feature is [committed to be GA by Q4](https://gitlab.com/gitlab-org/gitlab/-/issues/532507#note_2511480980) so we need to create a backup and restore solution for customers.
