Packages for Python 3.11 currently missing in the openSUSE Leap distribution.

The default Python version in openSUSE Leap distributions (15.5 and 15.6) is still Python 3.6, which is a little bit dated, to put it mildly. There are more recent Python versions in the distribution, including Python 3.11. But not all third party packages are yet available for this newer version. The present project aims to fill the gap. Depending on availability, most packages are either modified versions from the distribution or backports from openSUSE Factory.
