dev-python/python-ly: enable py3.11

- python 3.11 support enabled
- few style changes common to dev-python category
- remove comment about missing tests in pypi tarball, because we use
  sources from github
- add dev-python/lxml test dependency, however, tests are still
  restricted, because I failed to make them work properly. My attempt is
  described in upstream issue [1].
