I am seeing an issue where this migrations fails because the
`metadata._typeorm_migrations` table does not exist.
```pgsql
copy _typeorm_migrations from metadata to core
query failed: SELECT * FROM metadata._typeorm_migrations ORDER BY id ASC
error: error: relation "metadata._typeorm_migrations" does not exist
[Nest] 430 - 06/01/2025, 10:22:35 PM ERROR [CopyTypeormMigrationsCommand] Failed to copy migrations: relation "metadata._typeorm_migrations" does not exist

```
I _think_ this table is not meant to exist anymore - which means that
anyone who is onboarding into the project will run into an issue unless
we handle the case where the table doesn't exist.
We need to handle both the existing case and the non existing case to
support people who _do_ have metadata._typeorm_migrations` to migrate.
