Subject: [PATCH] Restore MySQL data after renaming containers (#75)

When we changed the docker-compose project name from boulder to labca, we should
have also taken care of moving existing DB data from the old docker volume to the
new one. Now we do this in case anyone else upgrades from a pre-v23.05 release.

Also, clean up gorp_migrations table so the in-place upgrades will actually work.
