Change: bulk format using ruff format

[NiklasHargarter]

What

formatted using ruff format
Merged implicitly concatenated strings into single lines/f-strings for better readability.
Normalized whitespace (removed unnecessary blank lines after class definitions and within methods).

Manual Fixes: In test_helper.py trailing commas were automatically formatted into explicit single-item tuples which is wrong. so removed the commas. And grammar.py some r strings were not combined properly by ruff.

Now black is happy, ruff is happy. And all tests pass.
