textproc/py-mkdocs-autorefs: Update to 1.4.2

* Remove the no longer needed workaround for deleting remnants of the
  Mypy cache because this is fixed with this version.

* Also adjust USES=python accordingly, because Python 3.8 is no longer
  present in the ports tree after ca15850a2b while I'm here.
