Fix position of bubble education views on large screen in RTL

In large screen or landscape, the width of the education view is not
full width, so we need to position it on the edge of the screen
when in RTL. It naturally does this in LTR.

Bug: 233408508
Test: force user education to show for bubbles, check how it appears
     in RTL & LTR on: large screen portrait & landscape, and portait
     and landscape on phone.
