rename hairclip -> hair clip

Posted under Tags

BUR #58602 is pending approval.

create alias hairclip -> hair_clip
create alias parallel_hairclips -> parallel_hair_clips
create alias unworn_hairclip -> unworn_hair_clip
create alias no_hairclip -> no_hair_clip
create alias flower_hairclip -> flower_hair_clip
create alias heart_hairclip -> heart_hair_clip
rename too_many_hairclips -> too_many_hair_clips

This always bothers me when tagging even though there's an alias. It's 5x more common to spell hair clip with a space.
This is also the primary spelling on Wikipedia, Wiktionary, Cambridge Dictionary, Collins Dictionary, and Oxford English Dictionary.
However, on Google, there are 8% more results for the spaceless version.

Hairpin is fine as-is because it's 51x more common to spell with no space. Hairband and hair band are about the same, but since 2019, hairband is the more popular spelling.

There are also a few character tags that can be moved manually except for the one that's an alias.
