Free mypy

Tested with version 0.910

This takes care of mypy failing on python 3.11

I'm eagerly monitoring python/mypy#11158 as I would have bumped to 0.920 once it's available, but freeing it is fine for me as well. I'm actually surprised that 0.910 works with Python 3.11 as I expected python/mypy#11531 / python/mypy#11560 to be required (to get typed_ast 1.5.1 with python/typed_ast#176) but that's not part of a release yet. 🤔

If it starts causing issues again I'll pin it again to a version. Happy to see those failed checks gone 😁

Recent versions of mypy only require typed-ast if you're running with Python 3.7 or lower, or if you want to check Python 2 code :-)

Right. python/mypy@4adb5e4 is the crucial change. The compilation error actually only affects 0.812 while 0.900 and newer just do not even try to install typed-ast on Python 3.11. 👍
