Chore/update linting tools

[mcocdawc]

Description

Updated and unified the pre-commit hooks in all earthkit packages.
Some of them were failing the test suite just because of the pre-commit hooks.
Fixing this it was a good opportunity to unify settings.

Uses now ruff for formatting (former black), linting, and import sort (former isort)
