<?><?><?><?> (EXAMPLE)

         To login in to a docker/OCI registry:
         $ apptainer registry login --username foo docker://docker.io
         $ apptainer registry login --username foo oras://myregistry.example.com

         Note that many cloud OCI registries use token-based authentication. The token
         should be specified as the password for login. A username is still required.
         E.g. when using a standard Azure identity and token to login to an ACR
         registry, the username '00000000-0000-0000-0000-000000000000' is required.
         Consult your provider's documentation for details concerning their specific
         login requirements.
