modernize the pre-commit hooks

[keewis]

I'd nowadays use:

• ruff instead of flake8, isort (and seed-isort-config)
• the black-pre-commit-mirror repository to be a little bit faster (could use ruff-format as well, but I personally don't)
• prettier to format json, yaml, and markdown (and other web formats, but we don't seem to have any of those here)
• taplo to lint / format toml
• validate-pyproject to validate the project / build-system table in pyproject.toml

I didn't enable the pyupgrade / relative-import rules that I usually would, because this would mean a lot of additional changes. Do tell me if you'd be fine with those, though, and I'll switch them back on.

Oh, and I didn't upgrade mypy because there's a two errors and a bunch of notes – which I guess is what causes #764 to fail (and I don't know enough about type checking to fix those errors myself):
