docs: Check whether a short number is a possible number when dialled from a
      region. This provides a more lenient check than
      is_valid_short_number_for_region.
  
      Arguments:
      short_numobj -- the short number to check as a PhoneNumber object.
      region_dialing_from -- the region from which the number is dialed
  
      Return whether the number is a possible short number.
