Followup to ba65982fac. parona made a fair point
that a revbump is technically warranted given that with USE=python, we may
get an additional impl installed outside of what PYTHON_TARGETS covered
(e.g. if configure picks up Python 3.12, builds & installs that, then the
proper Python impl builds do Python 3.11).
Revbump for correctness accordingly. After he said it, I realised it wasn't
just a technicality, but actually pretty plausible as well.
