fix: expose google workspace inputs

[LuD1161]

Summary

• expose input ports for the Google Workspace user delete component so the builder shows proper wiring
• keep component docs available for the new metadata field and require a secret id in validation

Testing

• not run

Now it shows how to create the service account to make this work. Eventually all this would go into the docs and this documentation would be a very short snippet, not the big one as you see here.
