chore(tooling): add missing code formatting checks (`ruff format --check`)

[danceratopz]

#1326 replaced flake8, isort and black with ruff 🚀

While tox -e static runs ruff check which handles the checks isort and flake8 were previously responsible for:

execution-specs/tox.ini

Lines 11 to 22 in 51cabd8

	[testenv:static]
	extras =
	lint
	optimized
	test
	doc
	commands =
	codespell -I whitelist.txt {tox_root}/src --skip '{tox_root}/src/ethereum_spec_tests'
	ruff check src --exclude src/ethereum_spec_tests
	mypy src --exclude "src/ethereum_spec_tests/*" --namespace-packages
	ethereum-spec-lint
	uv lock --check

tox doesn't have the checks that black previously performed, i.e., we should still add:

ruff format --check src --exclude src/ethereum_spec_tests

Unfortunately, as it stands, this would reformat 389 files.
