Simpler D10 port using MenuLinkManipulator patch

I've prepared a port to D10 that makes use of the MenuLinkManipulator patch in https://www.drupal.org/project/drupal/issues/2466553 🐛 Untranslated menu items are displayed in menus Needs work . This results in a much simpler implementation (though I have admittedly taken out options - this version just does token replacements).
