drm/ci: disable broken MR check in sanity job

GitLab recently changed the required permissions for the
are-developers-allowed-to-push-to-my-MR check:
https://gitlab.freedesktop.org/freedesktop/ci-templates/-/issues/81

Until that’s resolved, disable the check - it’s mostly obsolete anyway.

Based on https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/37782
