Felix Seifert 9f6f312a31 chore: update all versions of actions/checkout to v4 (#199) ...

In this PR, I update the `actions/checkout` versions. When I recently
started using this action, I was confused about whether it works with
the newest checkout action. I tested it and everything is fine. For
future users, we should display examples with the newest versions.
