#### Testing the changes
- I tested the changes in this PR: **briefly**
- I built this PR locally for my native architecture, amd64

This package was strange, when I was updating to python3.11, byte-compile thrown errors about syntax, code looked like python2

A patch file from https://github.com/void-linux/void-packages/pull/40408.patch is attached
