Enable pre-commit autoupdate PRs (#929)

# Pull Request

## Title

Enable pre-commit autoupdate PRs

---

## Description

Adds configs for pre-commit.ci to use to scan our repo and automatically
submit PRs to update pre-commit hook version monthly.

---

## Type of Change

- ✨ New feature

---

## Additional Notes (optional)

This also enables autofix PRs to hopefully improve the turnaround time
on PR reviews by automatically applying formatting fixups to a PR.

This could get confusing or annoying if PR authors don't locally pull
after fixes are applied or if the formatters do something drastic that
we aren't anticipating, so we may consider to disable this in the future
as well.
