docs: Return a single instance of the model queried by ID.
  
          Args:
              record_id (int): Integer representation of the ID to query on.
  
          Keyword Args:
              execute (bool, optional):
                  Should this method execute the query or return a query object
                  for further manipulation?
  
          Returns:
              cls | :py:class:`peewee.SelectQuery`:
                  If ``execute`` is ``True``, the query is executed, otherwise
                  a query is returned.
  
          Raises:
              :py:class:`peewee.DoesNotExist`:
                  Raised if a record with that ID doesn't exist.
