Adopt `ruff` for code linting and formatting

At the moment, we have several linters, formatters, and checkers of Python code (`black`, `isort`, `flake8`, `mypy`, `bandit`, `vulture` etc.). With [`ruff`](https://github.com/astral-sh/ruff), we would have a single tool that covers all of the above (and more). It seems like a good choice adopting it for the `pddl` project. Thoughts?
