Description

Pre-deployment checklist

ensure all subtasks below have passed QA stage (it's ok if QA in production hasn't happened yet)

Acceptance criteria

Deploy language button to all logged-in users
Decide whether https://gerrit.wikimedia.org/r/c/mediawiki/extensions/UniversalLanguageSelector/+/688994 needs to be backported. It is needed for the A/B test so should be present on the test wikis prior or as part of deployment. (deployed everywhere)
Decide if fix for https://phabricator.wikimedia.org/T282540 needs to be backported (available 27th earliest)
Decide if any patches for https://phabricator.wikimedia.org/T276561 need to be backported (without backport will go out on 10th June)
Deploy button to test wikis, along with A/B test setup (A/B test will run on users of the test wikis only)
100% to all anonymous users
A/B test for logged-in users
Make sure that the language button is not available on wikis where a language button appears next to personal tools (e.g. Wikimedia Commons, Wikidata.org)
