980edd6b2c CI: Add Python 3.11 (Kristaps Kaupe)

Pull request description:

  All that was needed was upgrade of [bencoder.pyx to 3.0.1](https://pypi.org/project/bencoder.pyx/3.0.1/). It supports Python versions from 3.6 to 3.11.

  Note that I haven't more carefully tested JM with Python 3.11, just made sure it installs and CI tests passes.
