Currently (as of 07/28/23), in a roachtest failure on 23.2 (like #107862), the generated Grafana link in the "Help" section redirects you to cockroachlabs.com - instead of testeng Grafana.

Looking at the issue linked above as an example, we see the following vanity link for Grafana: https://go.crdb.dev/p/roachfana//1690711427218/1690713270780

Instead, we should be seeing the following:
https://go.crdb.dev/p/roachfana/teamcity-11114747-1690696061-26-n5cpu4/1690711427218/1690713270780

The cluster name seems to be empty - clusterName in generateHelpCommand.
