Closing: ruff is deliberately pinned <0.15 in pyproject.toml, and 0.15's formatter reflow fails the required check job (Would reformat: tests/ui_and_conv/test_native_update_parity.py). Added a Dependabot ignore for ruff >=0.15 to respect the intentional ceiling.

[dependabot]

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
