Pylint with Python3.10

[kralka]

Pylint also with Python3.10. Other workflows (mypy, pytest...) are still run against Python3.9. Suggested at #87 (comment)

@jmichelp Should we also bump Python version for other workflows?

Interestingly the workflow name is shortened into "3.1" instead of "3.10".

It depends which python version we use most.
The idea here is to pylint with the all supported versions and one version above so that we can can earlier issues when we bump the version. The other tests should use the python version we currently rely on.

It got parsed as a float.

I would say we rely on 3.7 (still :/), 3.8 for Ubuntu 20.04LTS, 3.10 for Ubuntu 22.04LTS. While 3.11 is still alpha.

I suggest to bump Python version in workflows to 3.10 and when 3.11 is out to add it to the pylint matrix.

Sounds good.
Going back in versions wouldn't make sense.

Be careful that tensorflow sometimes needs time to fully test a new version of python interpreter. Adding 3.11 too early could result in a missing package.

Good point, but if that happens the PR fails and we wait a bit more (nothing breaks).
