Add support for python 3.11

[laurentS]

Just adds a run with the newly released python 3.11. Hopefully everything should run smoothly 🎿 !

[laurentS]

The tests are a bit cheeky (from the logs of the python 3.11 execution):

The currently activated Python version 3.11.0 is not supported by the project (<3.11,>=3.7.2).
Trying to find and use a compatible version. 
Using python3.8 (3.8.10)

This PR cannot be fixed until the sdk is upgraded to support python 3.11.
Right now poetry update fails with the following error:

The current project's Python requirement (>=3.7.2,<3.12) is not compatible with some of the required packages Python requirement:
  - singer-sdk requires Python >=3.7.1,<3.11, so it will not be satisfied for Python >=3.11,<3.12
  - singer-sdk requires Python >=3.7.1,<3.11, so it will not be satisfied for Python >=3.11,<3.12

Because no versions of singer-sdk match >0.12.0,<0.13.0 || >0.13.0
 and singer-sdk (0.12.0) requires Python >=3.7.1,<3.11, singer-sdk is forbidden.
So, because singer-sdk (0.13.0) requires Python >=3.7.1,<3.11
 and tap-github depends on singer-sdk (>=0.12.0), version solving failed.

Waiting on meltano/sdk#1115

@laurentS shouldn't the tests be failing then?

Sorry, I realise my messages were confusing. Basically CI passes because poetry falls back to python 3.8 in the 3.11 run. The error in my last message was from a run on my machine after adjusting the pyproject.toml file and trying to resolve dependencies again with poetry update (which does not happen in CI).

So I think we don't have too many options, wait for sdk which is waiting on pyarrow. Their build is passing as of 2h ago, so it shouldn't take too long before they push a new release.

Let's wait until we have a stable release for the SDK :)

Done, using sdk 0.13.1 now, which includes python 3.11 support, despite what the release notes say.
