Add notes around external registry authentication
What does this MR do?
The configuration instructions for configuring external container registries only implicitly notes that the external registry service must be configured to use GitLab's JWT authentication endpoints.
These changes add explicit notes on what the external registry
configuration for auth should look like, and the image naming
limitations one will run into if it is not configured.
