Bumped minimal Python version to 3.9

* Python 3.8 is now end of life [Link]
* changed occurrences found with `git grep -P '[^\d\.]3\.8[^\d]'`
* so doing, removed unused branch in `glances/outputs/glances_restful_api.py`
* branch introduced by f654558
* ruff also needs a bump; i.e, `s/py38/py39/`
* not done yet, since it needs to clear out warnings.
