[tests] Update flake tests on jenkins CI

Backport change from master to tests.

several flake8 modules fails with new flake8 6.0.0
which needs Python 3.8.1. Jenkins CI does not reflect
the right Python version. Therefore only add quotes check
for Python < 3.8 which uses flake8 5.0.4.

- Use flake8-quotes with Python < 3.8 only
- Adjust flake8-quotes to >=3.3.0
- Adjust importlib-mtadata for Python < 3.8
- Test flake8 and hacking for the lowest and highest available Python
