chore: update github-actions

[reneleonhardt]

Chores

• Update github-actions
• Let dependabot update github-actions and pip

[reneleonhardt]

Notes

• It would be great if unnecessary CI jobs would be skipped in forks (i.e. safety requiring license keys)
• It would be nice if main.py wouldn't fail if running in forks (akaihola/darker is hardcoded there, GITHUB_REPOSITORY contains the actual repo)

• Update github-actions

@reneleonhardt, do you mean to update all 3rd party GitHub actions used in workflows to most current versions?

• Let dependabot update github-actions and pip

I assume this would be done by following the Enabling dependabot for your repository instructions?

• It would be great if unnecessary CI jobs would be skipped in forks (i.e. safety requiring license keys)

Do you have a recipe for how to make this happen?

• It would be nice if main.py wouldn't fail if running in forks (akaihola/darker is hardcoded there, GITHUB_REPOSITORY contains the actual repo)

Cool, that makes sense. So essentially just replace akaihola/darker by GITHUB_REPOSITORY everywhere in workflows?

@reneleonhardt ah, oops, it's late and I thought I was reading an issue and not a PR – so you did most of this already in your changes. Thanks!
