docs: Only return translated objects which of the given languages.
  
          When no language codes are given, only the currently active language is returned.
  
          .. note::
  
              Due to Django `ORM limitations <https://docs.djangoproject.com/en/dev/topics/db/queries/#spanning-multi-valued-relationships>`_,
              this method can't be combined with other filters that access the translated fields. As such, query the fields in one filter:
  
              .. code-block:: python
  
                  qs.translated('en', name="Cheese Omelette")
  
              This will query the translated model for the ``name`` field.
