We already show the OIDC sign-in configuration on the /deployment/userauth page. We also show if GitHub sign-in is configured. It would be nice to see the allowed GitHub organizations and if signups are allowed on this page.

We are currently showing no options to configure, which is wrong as we do have the configuration for GitHub.
