I tried this in #1009, we got no benefit from that.
@derek-ho could you please add more details to the PR? What was fixed? How?

@Yury-Fridlyand - edited the description. This adds to the workflow to add a "failed-backport" label on the PR if a backport fails. This will help us filter by those PRs which failed the backport and reconcile before release/for CVEs. Before hand, a backport would fail silently/not show any indication outside the PR that the backport failed.
