Remove `:auth, :enforce_oauth_admin_scope_usage`

`admin` scope has been required by default for more than a year now
and all apps that use the API seems to request a proper scope by now.

 Authentication is required and the user must be an admin.
 
-Configuration options:
-
-* `[:auth, :enforce_oauth_admin_scope_usage]` — OAuth admin scope requirement toggle.
-    If `true`, admin actions explicitly demand admin OAuth scope(s) presence in OAuth token (client app must support admin scopes).
-    If `false` and token doesn't have admin scope(s), `is_admin` user flag grants access to admin-specific actions.
-    Note that client app needs to explicitly support admin scopes and request them when obtaining auth token.

 ## `GET /api/pleroma/admin/users`
