docs: Use this method to get basic info about a file and prepare it for downloading.
  
      For the moment, bots can download files of up to 20MB in size. On success, a File object is returned. The file can
      then be downloaded via the link https://api.telegram.org/file/bot<token>/<file_path>, where <file_path> is taken
      from the response. It is guaranteed that the link will be valid for at least 1 hour. When the link expires, a new
      one can be requested by calling getFile again.
