[📑🐞 Docs Bug]: Readme: List of official generator templates points to archived repos

Start in the README section linked as “List of official generator templates” and inspect each listed repository's current status. Verify which generator templates are still official and available, then update the list so it does not point to archived repositories. Done means the README links and surrounding descriptions accurately reflect the available official templates.
