Alias strapless swimsuit to strapless one-piece swimsuit

BUR #19492 has been approved by @nonamethanks.

create alias strapless_swimsuit -> strapless_one-piece_swimsuit

I'm surprised strapless swimsuit hasn't been touched yet when modifying the specific swimsuit tags (especially the color specific ones) to refer to one-piece swimsuits only, especially since there are a few posts depicting two-piece swimwear mistagged strapless swimsuit when they should have been tagged strapless bikini instead.

Alright, just finished going through strapless swimsuit and removed any posts where strapless bikinis are incorrectly tagged as "strapless swimsuit", now making the tag ready for aliasing.
