Fix nextcloud-onlyoffice InfoInhibitor alerts
We still frequently get these alerts:
[FIRING:1] (InfoInhibitor pending nextcloud-onlyoffice stackspin-apps nc-onlyoffice-documentserver-758944b8b4-ktxls stackspin/kube-prometheus-stack-prometheus none)
alertname = InfoInhibitor
alertstate = pending
container = nextcloud-onlyoffice
namespace = stackspin-apps
pod = nc-onlyoffice-documentserver-758944b8b4-ktxls
prometheus = stackspin/kube-prometheus-stack-prometheus
severity = none
Annotations
description = This is an alert that is used to inhibit info alerts. By themselves, the info-level alerts are sometimes very noisy, but they are relevant when combined with other alerts. This alert fires whenever there's a severity="info" alert, and stops firing when another alert with a severity of 'warning' or 'critical' starts firing on the same namespace. This alert should be routed to a null receiver and configured to inhibit alerts with severity="info".
