Revert "[CLOUD-80] authz: update `authzQuery` to align with our access policy for user-added repos "
Created by: unknwon
Reverts sourcegraph/sourcegraph#26193 because currently our single-thread permission syncer could not keep up (takes too long > 5 minutes to make a repo show up for the user), and some unidentified slowness in user-centric syncing.
