fix(appset): dont requeue appsets on status change

[rumstead]

When an applicationset is requeued and there are no changes to the child application's spec but there is a change to their sync status, eg progressing, healthy, outofsync, the applicationset will be requeued twice because the applicationset's status is patched with the sync status of the underlying applications.

Before changes

updating an applicationset when an underlying application has changed status

time="2025-01-02T16:55:06-05:00" level=debug msg="received update event" applicationset=argocd/cluster requeue=true
time="2025-01-02T16:55:06-05:00" level=debug msg="received update event" applicationset=argocd/cluster requeue=true

After changes

updating an applicationset when an underlying application has changed status

time="2025-01-03T14:46:00-05:00" level=debug msg="received update event" applicationset=argocd/cluster requeue=true
time="2025-01-03T14:46:00-05:00" level=debug msg="received update event" applicationset=argocd/cluster requeue=false

It would be great if this could be cherry-picked into 2.14
