Frescobaldi and Python 3.11

[Jean Abou Samra]

Hi,

Frescobaldi is facing an issue that prevents it from launching
under Python 3.11 beta.

https://github.com/frescobaldi/frescobaldi/issues/1453

Python 3.11.0 will be released tomorrow, and it's a matter
of weeks until Fedora 37 is also released, with Python 3.11.0.
Thus the Frescobaldi Fedora package will be unusable soon
on current Fedora versions. (The upstream Fedora issue is
https://bugzilla.redhat.com/show_bug.cgi?id=2121995).

Of course, over time, other distributions will start switching
to Python 3.11 as well.

I'm just raising this significant issue here for visibility,
in case there are PyQt experts out there who have time
and interest to track down this bug.

Thanks,
Jean
