Add python 3.11 wheels

[mayeut]

Now that cpython 3.11.0rc1 is out (ABI stable), we can publish cp311 wheels.
This bumps cibuildwheel to 2.9.0 which now builds cp 3.11 wheels.

@mayeut @methane Hey there! I noticed the wheels are still missing on pypi.

We noticed this by having 30 seconds extra build time in our github actions workflow which shows we need to build the wheel every time:

@anderssonjohan Try 1.0.5rc1.

[anderssonjohan]

Thanks for the quick reply! Then we'll wait for 1.0.5 to be released, no worries.
(This affects us when installing poetry via the actions-poetry GitHub Action so we are a bit limited pinning an rc version in this particular case.)

[methane]

I have released v1.0.5.
