Bug: reorder_graphql_submenu_items() strips out other 3rd-party submenus.

[justlevine]

Issue

When activating the plugin, other submenus registered to the graphql-ide menu get stripped out.

This is caused by WPGraphQLIDE\reorder_graphql_submenu_items

Expected Behavior

Other GraphQL submenu items should be preserved.

To test

1. Register a custom submenu:

   add_action( 'admin_menu',
     static function() {
       add_submenu_page(
         'graphiql-ide'
         'SnapWP',
         'SnapWP',
         static function() => echo '<div>Hello World</div>',
         999
       );
     }
   );

2. Confirm the menu item exists when WPGraphQL IDE is deactivated.
   

3. Activate WPGraphQL IDE and watch it disappear
   

Additional notes.

This can be temporarily worked around by setting the admin_menu callback to a priority of > 100 so it runs after WPGraphQL IDE bugs out.
