Need to specify the python and flake8 version based on the project

Line 23 in 89b1a3d

python-version: '3.10'

Since flake8 v6.0.0, some valid python syntax is flagged which causes workflows to fail. Specifically type hints comments, which are valid in all current versions of python according to PEP 0484. This is all thanks to this pull in pyflakes, PyCQA/pyflakes#684

Unfortunately several of our projects require support of Python 2.7 so cannot just switch to new type hint annotations. Seems like a hasty and poorly thought out decision to completely drop support for something that is valid and acceptable syntax.

Perhaps some better options:

• Qodana can be used to run jetbrains (pycharm) inspections from github workflows. Python is in early access stage.
• Run PyCharm/Jetbrains code inspections from command line. (https://www.jetbrains.com/help/pycharm/command-line-code-inspector.html#inspection-profiles)

The solutions here, (https://unterwaditzer.net/2019/mypy-and-python2.html), may also work for flake8.
