SVGs in page language are live on the beta cluster and seem to work well so far. This ticket is to roll it out on all wikis. Here's the proposed break-out for rollout to happen:
 All non-Wikipedia wikis
 All wikis
I don't mind if the order changes as long as it goes live everywhere.
Things to monitor:
* [[ https://grafana.wikimedia.org/dashboard/db/save-timing?panelId=22&fullscreen&orgId=1 | Frontend save timing ]]

* `slow-parse` log channel
