Critical issue using PyQt6-Qt6 on older distros

[Phil Thompson]

There is a new Linux wheel at the local PyPI server...

https://www.riverbankcomputing.com/pypi/

There are also wheels for the upcoming QScintilla v2.14.1 which should 
also work on older Linux distros.

I'd appreciate any testing, particularly on distros with old versions of 
GLIBC but also those with OpenSSL v3.

The solution was to switch the build system to openSUSE 15.4 which has 
an old GLIBC but is still officially supported by Qt v6.5...
