We use https://github.com/browniebroke/pre-commit-autoupdate-action in the [pre-commit updater workflow](https://github.com/target/make-python-devex/blob/main/.github/workflows/pre-commit-updates.yml#L22), but it's actually _really_ simple. Even the author of it seems to have moved on, creating and using their own version that inlines the action in <https://github.com/browniebroke/github-actions/blob/main/.github/workflows/pre-commit-autoupdate.yml>.
