Support for running PR checks without extra steps

[terlar]

Would it make sense to add some configuration to allow running the PR checks without extra manual steps, e.g. with one of the solutions suggested here:
https:/peter-evans/create-pull-request/blob/main/docs/concepts-guidelines.md#workarounds-to-trigger-further-workflow-runs

Personally I went for the GitHub App generated token, which worked very well.

Basically what is outlined here:
https:/peter-evans/create-pull-request/blob/main/docs/concepts-guidelines.md#authenticating-with-github-app-generated-tokens

So perhaps we could let users configure app_id and private_key and if they do, the necessary steps would be added.

Good idea, is this issue solved by #22?

Yeah, that would work.

In my preferred approach you would generate an app token like this:

     - name: Generate App Token
        uses: tibdex/[email protected]
        id: generate-token
        with:
          app_id: ${{ secrets.APP_ID }}
          private_key: ${{ secrets.APP_PRIVATE_KEY }}

And then pass it to the action via token instead.

I guess since peter-evans/create-pull-request decided to leave that part outside it makes sense to do the same.
