docs: Gets a valid number for the specified region and number type.
  
      If None is given as the region_code, then the returned number object
      may belong to any country.
  
      Arguments:
      region_code -- The region for which an example number is needed, or None.
      num_type -- The type of number that is needed.
  
      Returns a valid number for the specified region and type. Returns None
      when the metadata does not contain such information or if an invalid
      region or region 001 was specified.  For 001 (representing
      non-geographical numbers), call example_number_for_non_geo_entity instead.
