Add support for Python 3.11 (#348)

Include CI jobs and trove classifier. Bump some CI checks from "3.10" to 
"3.x" (currently 3.11). Didn't do it for `.github/workflows/style.yml`, 
because that would require upgrading pylint to a later version to 
support 3.11 but also introduce failing lint rules. Also bump some GitHub 
Actions to newer versions.
