[Lint] Use ruff formatter and pre-commit framework

[tovaz92]

This PR aim to:

1. substitute flake8 linter with ruff linter-formatter
2. integrate pre-commit
3. add GitHub action that check the pushed files at every commit

Note once pre-commit is installed:

• pre-commit-hooks will run: trailing-whitespace, end-of-file-fixer, check-yaml and will run on all committed files
• ruff-pre-commit will run: ruff-check, ruff-format (only on .py files).

Installation:
Follow steps below to make pre-commit operative:

1. To install pre-commit: pip install -e ".[precommit]" (otherwise if the user want to install aqua with environment.yml, uncomment the relative line)
2. To "switch-on" pre-commit, install it with: pre-commit install
3. Once installed, at every commit, pre-commit will run on the pushed files and will block the commit if the checks do not pass.
4. If the user want to uninstall pre-commit definitively run: pre-commit uninstall or, if want to temporarily "switch-off" (need to be reinstalled after the unchecked push):

After a chat with the group, we will go for Ruff as it is much more flexible for our needs.

ok, the action seems to behave as we expected. It is failing and showing all the problems. I am tempted to exclude the __init__.py files though.
