[Code] Add python linter

[valentimarco]

2 possibility:

• Git hook (before commit, linter run and format the code)
• Action (After commit)

[pieroit]

Action for sure! We were using pre-commit at the start of the project and no contrib wanted to adopt it

I suggest using this: https://github.com/astral-sh/ruff-pre-commit and https://github.com/chartboost/ruff-action
