Motivation for this change

Before these changes it was required to enable postgres yourself and set up a role and everything to be able to use it.

After these changes it does all of this for you:

  # Gitea
  services.gitea.enable = true;
  services.gitea.appName = "My Git Service";
  services.gitea.rootUrl = "http://git2.example.com/";
  services.gitea.database.type = "postgres";
  services.gitea.database.password = "this-is-my-database-password";
