Description of problem

Seen in a 4.15.19 cluster, the PrometheusOperatorRejectedResources alert was firing, but did not link a runbook, despite the runbook existing since MON-2358.

Version-Release number of selected component

Seen in 4.15.19, but likely applies to all versions where the PrometheusOperatorRejectedResources alert exists.

How reproducible

Every time.

Steps to Reproduce:

Check the cluster console at /monitoring/alertrules?rowFilter-alerting-rule-source=platform&name=PrometheusOperatorRejectedResources, and click through to the alert definition.

Actual results

No mention of runbooks.

Expected results

A Runbook section linking the runbook.

Additional info

I haven't dug into the upstream/downstream sync process, but the runbook information likely needs to at least show up here, although that may or may not be the root location for injecting our canonical runbook into the upstream-sourced alert.
