feat: cmd helpers for migration down/up/status

[aeneasr]

See https://github.com/ory-corp/cloud/issues/7350

This migrator is compatible with PrepareMigrations which is something we still use for very old Ory Hydra versions. The goal is to use this migrator in all projects.

I had to remove --version abc,def again because the pop migration box is only able to roll forward or roll backwards, but not able to pick specific versions to roll back. That would need to be done manually then.
