  <issue>
  remove ask engine
  Reasons:
  
  1. User Tracking via query parameters.
  
      Example Query: [!ask best museums in Köln](https://searx.be/search?q=%21ask+best+museums+in+K%C3%B6ln&category_none=&language=auto&time_range=&safesearch=0&theme=simple)
  
      Notice the ```euid=some_id``` at the end for most urls.
  
  2. Very bad results - Something must have changed.
  
     Example Query: [!ask "yt-dlp"](https://searx.be/search?q=%21ask+%22yt-dlp%22&category_none=&language=auto&time_range=&safesearch=0&theme=simple)
