NOTE: Confirm with Olga that a future A/B test is not needed before removing this code.
**Context**
Last time we removed A/B test code in config and Vector, [[ https://phabricator.wikimedia.org/T337955 | it caused the edit button to disappear ]]. We want to test thoroughly before removing completed Zebra A/B test code this time around.
**Success Criteria**
[ ] Completely remove default Zebra AB Test configuration lines in mediawiki config and beta config
[ ] Completely remove Zebra A/B test -related lines in Vector
[ ] Test in Beta for any misfires or JS errors
[ ] Run pixel - make sure all green
[ ] Merge to prod
*Jon's note: $wgVectorZebraDesign would be kept. Code relating to VectorWebABTestEnrollment wouldn't
