Add `actionlint` with `pre-commit`: a static checker for GitHub Actions workflow files

[jbampton]

actionlint is a static checker for GitHub Actions workflow files

Check out the actionlint playground:

https://rhysd.github.io/actionlint/

https://github.com/rhysd/actionlint/blob/v1.7.7/docs/usage.md#pre-commit

repos:
  - repo: https://github.com/rhysd/actionlint
    rev: v1.7.7
    hooks:
      - id: actionlint

So the hook will need to be added to the pre-commit config and then all the actionlint lint errors will need fixing

The next document describes all checks done by actionlint with example inputs, outputs, and playground links:

https://github.com/rhysd/actionlint/blob/v1.7.7/docs/checks.md

Comes with a config file that you can customize:
