This PR improves the sync_argocd_apps.sh script in the following ways:

• Only wait for each app to become healthy one time. Previously, we waited once after the sync (for the out-of-sync apps we just synced), and again for all the apps (even the ones which were not synced). Now we only do the second one.
• Increases the default ARGOCD_PRUNE_PROMPT_SECONDS to 60 seconds
• Improves the warning about pruning to explain that ArgoCD incorrectly displays resources that have argocd.argoproj.io/sync-options: Prune=false annotation as requiring pruning, when during an actual prune sync, they are not actually pruned:
  • Application CRD status.resources do not reflect argocd.argoproj.io/sync-options: Prune=false argoproj/argo-cd#17188
• Improves the force-sync feature to also work with namespaced resources:
  • (NOTE: we currently still only use it for ClusterPolicies, which are not namespaced)
