Resolve "Upgrade to kube-prometheus-stack 40.0.0 failing on staging"

Closes #1412 (closed)

I tested this script on my cluster:

❯ bin/upgrade-scripts/to-2.0/upgrade.sh
daemonset.apps "kube-prometheus-stack-prometheus-node-exporter" deleted
► suspending helmrelease kube-prometheus-stack in stackspin namespace
✔ helmrelease suspended
► resuming helmrelease kube-prometheus-stack in stackspin namespace
✔ helmrelease resumed
◎ waiting for HelmRelease reconciliation
✔ HelmRelease reconciliation completed
✔ applied revision 40.1.0
