Allow ok-to-test label to approve GitHub workflow runs for new contributors #25210

[MadhavJivrajani]

Original Issue: kubernetes/test-infra#25210

---

What would you like to be added:
The ability for Prow to approve GitHub workflow runs after the ok-to-test label has been added to a PR via GitHub's API https://docs.github.com/en/rest/reference/actions#approve-a-workflow-run-for-a-fork-pull-request

Why is this needed:
New contributors are blocked from running GitHub workflows even after a maintainer adds the ok-to-test label to a PR and contributors shouldn't need to rely on GUI access to approve workflow runs knative/test-infra/issues/3057

This is still valid request. There is a workaround, but it would be nicer if it was an actual feature in Prow.

I'm from volcano community, we also wish to have this feature. Currently, the first PR from outside contributors must be approved by our owner and then trigger the github workflows, which contain some e2e testing. We wish that when there is /ok-to-test labeled, the workflows can be triggered, not keep waiting for the owner to approve.

Hi, @tuminoid , how do you solve this problem? Are there any best practices so far? Thanks.

We are using this: kubernetes/test-infra#25210 (comment) as there is no better alternative right now.

OK, thanks, I think currently this action is enough to help our community, hope that prow will implement this feature one day. Seems that there are multiple communities hoping to combine prow and github workflows.
