Roll out of fix for Issue #22

[annethyme]

Hi QW team,

When confirming that issue #22 (QW-ACT-R37 yields false for positive for high opacity text on transparent background) is fixed, I found that the issue seems to still persist in the rule QW-ACT-R76 (TEXT HAS ENHANCED CONTRAST). Not that I am using the rule, but for consistency it would be nice to have the two rules aligned :)

And it seems that the fix has not yet been rolled out to the QW browser extension.
I do know that this one is often a bit behind on versions, so this is just FYI.
