ci: add annotation overview what failed/soft-failed/got cancelled during a build

Created by: jhchabran

Made some tests, anything happening to an agent (killed, lost, whatever) is being displayed as a failure, unless ... you start looking at the exit code at the very bottom or in the timeline. In some cases, it is being displayed as a "cancellation", but not in the one below where I manually killed the pod.

Looks like a failure 👇

But in reality👇
