Description

NOTE: Week of Oct 14

Deploy to Arabic, Vietnamese, French, Chinese, Indonesian wikis

Look at https://gerrit.wikimedia.org/r/c/operations/mediawiki-config/+/1189288 for reference.

We need to change the value from false to true for the participating wikis above.

Open question: does this change need to be backported?

Backport the change to Mediawiki config so that we can go live this week
Ensure that the latest branches contain all the necessary code (deploy a series of patches or one squashed patch) and latest bugfixes

At this point, should I be able to trigger the ImageBrowsing UI on one of the participating wikis (assuming I am on Minerva and use the ?imageBrowsing=1 URL param)?

I tried that here: https://vi.wikipedia.org/wiki/Paris?imageBrowsing=1&useskin=minerva, but so far I don't see any change.
