Change default Ruff hook to --fix-only

This should enable openapi-python-client to keep auto-fixing lints (like removing unused imports) but not fail to generate when unfixable lints are violated.

Since it's now unlikely for breaking changes to affect our usage (and by popular request), the upper bound of ruff has been lifted. Newer versions of openapi-python-client should no longer be required to support newer versions of ruff.
