What does this MR do?
Docs: Document how to migrate from bundled stateful services
- Document how to migrate bundled MinIO to Garage.
- Document how to migrate bundled Redis to Valkey.
- Document how to migrate bundled PostgreSQL to CloudNativePG.
The migration process can be desribed in three phases:
- Backup the instance.
- Provision external services and configure GitLab for them.
- Restore backup into new services.
The migration was tested on GKE 1.33 but should be provider agnostic.
Closes #6230
