I upgraded our Python toolchain:

• Replaced black, isort, and flake8 with ruff
• Type checking with pyright and Pylance VSCode extension
• All quality checks are checked before each commit with a pre-commit hook
• Added docs to support the use of the new tools

I also refined the simple example displayed on the README.md of the server Python package.

Actions items left (added to backlog, will be in a follow-up PR):

• Figure out how to embed Python examples/scripts in Markdown, e.g., pdoc's custom template
• Enable strict type checking for pyright and Pylance and resolve all current errors
• Enable type checking in the pre-commit hook
