monitoring: fix alert banner wording, link to grafana (!12045) · Merge requests · Administrator / sourcegraph · GitLab

Administrator requested to merge distribution/alerts-banner into master Jul 09, 2020

Created by: bobheadxi

for https://github.com/sourcegraph/sourcegraph/issues/12026

remove "are" from message so that the message is okay for all pluralities ("1 alert across 1 service currently firing", "12 alerts across 4 services currently firing")
trigger a window.location reload on /-/debug/* paths so that the link in the alert to grafana works (thread)
