As already mentioned in #331, this PR will switch 'black' fully to ruff.

There was a configuration for ruff already, but black was the main formater used before. This change removes black, reformats all files, fixes some linting errors, and enforces the rules in CI as well, so no drift happens now.

LGTM

@izar is that change to 'ruff' still wanted / needed? Just asking as when we merge in more things, we need to resolve conflicts and changes again.

hi @Alicipy - to be honest, I am still looking for a good reason to move to ruff. In my view, black is a perfectly fine solution, while ruff brings with it the whole Go environment - at least in my Ubuntu box.
I'll be glad to be educated on the advantages.

Hey izar,

yes, I would love to convince you, as I personally see a lot of advantages from ruff over black, also in the current project context:

• black is known for having some 'conflicts' with other tools, where the opinions what is 'right' differs. E.g., isort and black reorder things differently (needs config in isort), flake8/pycode and black use spaces differently, and the 'line length default' must handled at several places to be in sync
• ruff is a 'one in all' tool and reduces the number of tools to take care of, as it includes flake8 rules, isort rules, and other tool rules in itself, not needing to take care of tools for special reasons
• ruff is already included in the project for linting (it's a dev dependency already), we would just move formatting to it as well, removing black as a dependency

Not so relevant for the project as it's not really big, but:

• ruff is drastically faster, but not noteworthy here.
• ruff normally is completely compatible with black in default config (we still have some reformatting due to rules)

I don't get the point with Go unfortunately, as ruff is written in Rust and with 'pip install ruff', you get a prebuilt binary without any toolchain. Do you install it with snap, apt, or others?

If you'd still prefer black, that's fine, I was just asking for a decision so I know if we/I need to take care of this PR in any form
