chore(prlint): add need-xxx-reviews when building with github action (#35326)

### Issue # (if applicable)

Closes #35268.

### Reason for this change

When moving the builds to github actions, `need-xxx-review` labels were not added anymore.

### Description of changes
Fetch the build status from the github action, remove support for `StatusEvent` Github actions don't use it (only the direct Codebuild integration used it)



### Description of how you validated changes

Manually ran the script for a few PR's locally, updated unit tests.
