Update UXPL blue/green base with LMS/Studio (AC-517)
I recently fixed contrast issues in LMS/Studio many of which involve our blue and green. I brought over the blue and green from the UXPL but, to my surprise, they failed in various circumstances. I had to darken them each slightly.
As a result I need to update the UXPL values to match the new WCAG AA values from LMS and Studio.
