STYLE: Transition to ruff to enforce import statement sorting

Prefer using `ruff` instead of `isort` to enforce import statement
sorting.

`ruff`'s import sorting rules are near-equivalent to isort's when using
`isort`'s `profile="black"`:
https://docs.astral.sh/ruff/faq/#how-does-ruffs-import-sorting-compare-to-isort

Change the `tool.isort` section in `pyproject` so that the correspoding
tasks fall under the responsibility of `flake8`.

Adapt accordingly the pre-commit hook config file to apply the import
sorting to local files prior to commits.

Add a GHA workflow to apply the pre-commit hooks in order to ensure that
files modified across commits/in PRs comply with the expected
formatting.

Make the necessary style changes to make the `ruff` linter happy.
