Fix waiting for all pods having specified labels to be Ready

[prezha]

fixes #19288

this pr ensures that, when requested (via --wait flag), we wait until all (at least one) pods that have one of the CorePodsLabels in the kube-system namespace to be "Ready" or timeout

---

note: this pr should be merged after #20313 (and then rebase, solving expected conflicts)
