fix(color-contrast): ignore format unicode characters

[straker]

Format characters such as zero-width spaces were not checked in the nonBMP section of the unicode functions. I generated the regex by using regenerate and adding all format unicode to it.

In making this change I also discovered a bug in hasUnicode in that it only checked the first option that matched and not all options due to the early return style. So trying to check if a string contained punctuation while also checking if it had emoji would only ever check if it had emoji. Fixed that while I was here.

Closes: #3913

I'm okay with this approach, but had an idea you might appreciate.

Thanks. I do indeed like the idea much better
