Set review-workflow commit status for non-docs PRs in ci-build.yml

Non-docs PRs were being blocked by branch protection because nothing
was flipping the review-workflow status to success. stage-progression.yml
handles it for docs PRs, but ci-build.yml needs to handle the non-docs
path or those PRs can't merge.
