ICU-22721 Ignore CIFuzz spawned job and set delay for CI enforce checks job

[echeran]

CIFuzz jobs take a while to start. Until they do, within a workflow run, their neutral status and warning about "can't find configs" was causing the enforce-all-checks jobs to falsely fail.

The change looks fine, but the "docs minor fixes" ticket does not seem appropriate. Which ticket did you use for adding this check?

PR #3055 used the other release ticket, so I will now reuse that instead.

On further inspection with @FrankYFTang, I think the cause is different than what I identified. It looks like the CIFuzz Github Action is spawning another job (ex: a cleanup job? a reporting job?) every time a CIFuzz job finishes. That's what's interfering with our enforce-all-checks job. We can add it to the ignore list in the enforce-all-checks config. There's nothing wrong with setting up a delay of 2 minutes, but adding ClusterFuzzLite/CIFuzz to the ignorelist might solve the real problem.
