ANN: SIP v6.0.2, PyQt-builder v1.9.0, PyQt v5.15.3 and PyQt v6.0.2 Released

[Eric Larson]

Indeed it works for me if I use a clean venv.

It also works for me if I do `pip uninstall pyqt5 pyqt5-qt` then `pip
install pyqt5 pyqt5-qt` (even though it used the cached ones!), so looks
like that's a suitable workaround!
