Pre-releases of PyQt6 v6.1.0 etc Available

I have been using the prerelease wheels for over a year now on GitHub
actions to detect problems early, and I just got an error:

error: version lookup error: version `Qt_6.4' not found (required by
/opt/hostedtoolcache/Python/3.10.6/x64/lib/python3.10/site-packages/PyQt6/ (fatal)

So I think there is a bug with the latest 6.4 (?) prerelease wheels. It's
possible that there is some library that the wheels need that isn't
installed, but usually the error manifests differently in that case (or I'm
just missing it!).
