Support for Python 3.11

[blazewicz]

We're using invoke internally and it seems to be the last dependency incompatible with Python 3.11.

Error we're getting is pasted below, probably not the last one.

Traceback (most recent call last):

AttributeError: module 'inspect' has no attribute 'getargspec'. Did you mean: 'getargs'?

Similar to/dupe of #833, which contains workarounds (shimming getargspec or switching to a fork that applies the patch); #458 and #606 would fix this specific error if merged. Maintainers suggest this is blocked by #856 (remove python2 support).

I can confirm that issue was fixed with 8f6c061, we're awaiting for next release.

Any ideas when the next release will come?

Support for 3.11 was brought with release 2.0.0 🎉 thanks @bitprophet!
