Update pre-commit hooks, replace black with compatible ruff-format (#1892)

The [Ruff Formatter](https://docs.astral.sh/ruff/formatter/) is an
extremely fast Python code formatter designed as a drop-in replacement
for Black.

This leads to some adjustments as ruff already contains 2025 black style
updates, see astral-sh/ruff#13371
