Fixes #9132
Test Plan
I ran the tests specified in
CONTRIBUTING.md
cargo run -p ruff_cli -- check /path/to/some_files.py --no-cache cargo run -p ruff_cli -- format --check /path/to/some_files.py --no-cache cargo clippy --workspace --all-targets --all-features -- -D warnings RUFF_UPDATE_SCHEMA=1 cargo test pre-commit run --all-files --show-diff-on-failure
Note: In case no files are detected, either correctly formatted, changed, or unchanged, it does not display a message. Wouldn't it be better to show some message in this case?
