Adding QA/Blocked until we get Brave Talk enabled on main (staging) via Griffin. After it's enabled on staging, QA will be able to run through the above verification. Once we get closer to Brave Talk release date, we'll push the same change into production.

Removing QA/Blocked as brave/brave-variations#93 was merged into main (Griffin staging).
