- Add a few more hooks. These are all very fast, and I've found them useful in other projects:
- Autofixes:
- `trailing-whitespace`: fixes trailing whitespace
- `requirements-txt-fixer`: alphabetises items in `requirements.txt` files
- `end-of-file-fixer`: makes sure every file ends with a single newline character
- `mixed-line-ending`: Makes sure Windows users don't accidentally introduce CRLF line endings into a file that uses LF line endings
- None-autofixes:
- `check-yaml`: loads YAML files to validate syntax
- `check-toml`: loads TOML files to validate syntax
- `check-merge-conflict`: detects merge-conflict strings in files and blocks them from accidentally being committed
- `check-case-conflict`: checks for files with names that would conflict on a case-insensitive filesystem like MacOS HFS+ or Windows FAT; blocks them from being committed.
- Change the bot schedule to quarterly, to reduce noisy PRs
- Change the `black` language target-version to Python 3.10, synching the setting here with the changes that were made to our `pyproject.toml` file in #7538
