   which contains the revisionable update for link_override.
2. https://www.drupal.org/project/translatable_menu_link_uri/issues/3259442#comment-14930442
   which is the attempt to correct the update error introduced by
   translatable_menu_link_uri_update_8001 which tries to update
   menu_link_content_field_revision while it may be missing columns
   depending when your site started using the module.

The only change this commit makes is to start update hooks at
9001 for consistency with how hooks are usually numbered to start.
