Evaluate slow acknowledgments after successful polling.
wait.PollImmediate returns nil when CVO acknowledges after two minutes but before the 20-minute maximum. This code then skips the duration checks and returns nil, false, so delayed acknowledgments are not recorded as flaky. The error path only runs after the maximum timeout, so it cannot classify a successful slow acknowledgment.
Move the elapsed-time classification after PollImmediate returns. Preserve polling errors as failures.

But again, even raising the activeDeadlineSeconds threshold there isn't going to resolve the auth issue. This pull request addresses visibility on this issue by raising the observation timeout from the fatal threshold to a larger 20m cap.

That way, it's easier for someone to see what they'd need to bump the fatal per-platform cap too if they wanted to happy-up the job. Or that bumping the fatal per-platform cap is useless, and instead they need to dig in, identify something like the auth error, and get the registry-auth situation fixed.

The "Cluster version operator acknowledges upgrade" check waited only for
status.observedGeneration to catch up, within a fixed per-platform timeout.
The CVO advances observedGeneration only after the release payload has been
retrieved, verified, and accepted, so a slow release-image retrieval can blow
the timeout and fail the test even though the CVO is legitimately making
progress.
Make the wait tolerate a slow-but-progressing retrieval and fail fast only on a
genuine, non-recoverable payload rejection:
- succeed as soon as observedGeneration catches up (payload accepted);
- fail fast only when the CVO terminally rejects the payload -- ReleaseAccepted=False
with a reason retrying cannot fix (LoadPayload, VerifyPayloadVersion, or
PreconditionChecks);
- otherwise keep waiting up to a bounded hard cap. A RetrievePayload failure is
the CVO retrying a slow, unreachable, or transiently-erroring pull (including a
registry auth failure), which frequently succeeds on a later attempt, so it is
not treated as fatal; a pull that never succeeds still fails the test when the
cap elapses.
The previous revision failed fast on any ReleaseAccepted=False, but the CVO
reports ReleaseAccepted=False with reason "RetrievePayload" after each failed
retrieval attempt of a slow-but-eventually-successful pull, so that check would
still have failed the very runs this fixes. It also failed at the short
per-platform timeout when no target-matched ReleaseAccepted condition was yet
visible, but the CVO does not reliably publish its "retrieving" condition until
the first attempt completes, so a legitimately slow first pull would trip that
check too. Both are removed: the wait is now bounded solely by the hard cap and
fail-fast is reserved for terminal rejections. The 20m cap aligns with the
maximum acknowledgement wait in openshift#31654.
The fail-fast error surfaces only the ReleaseAccepted condition reason (a fixed
CVO step identifier); the raw condition message is omitted because it echoes the
requested image and retrieval error, which can carry internal registry
hostnames or other sensitive data into JUnit output and cluster events.
