Final call: "meta viewport does not prevent zoom" add SC 1.4.10

Hey folks,
Another final call. This time adding a WCAG 2.1 success criterion to one of
the rules that was created for WCAG 2.0 originally. This final call ends on
July 7th, please leave a review before that time if you have any comments.
