Fix cancelling of Pull Request builds when image build fails (apache#20939)

potiuk · web-flow · commit b171e03924fb · 2022-01-19T11:13:47.000+01:00
When image build fails, the pull request that triggered it should be cancelled. The apache#15944 introduced rewrite of the GitHub actions code but by mistake it also introduced a failure in cancelling the PR workflow by missing pipeline to jq. In most cases it did not matter, but it cause "wait for images" in PRs to run far longer than they should be. This PR restores cancelling feature.
