Gitlab repositories still reflected on projects page, cannot be updated accurately

I recently migrated Eclipse Dash from eclipse/dash to eclipse/technology/dash. While the Gitlab Namespace field worked a neat trick, the old Gitlab Repositories field doesn't accept the new format. If the data wasn't being showed on the public page this wouldn't be an issue, but it is being displayed and contradicts the (correct) Gitlab Namespace field. We should either hide the Gitlab Repositories field, or fix the logic so we can at least keep it up to date.
