create alias hoshino_ai_(oshi_no_ko) -> hoshino_ai
remove alias hoshino_ai_(oshi_no_ko) -> hoshino_ai
I'm not 100% sure about this one, there may be issues I'm not aware of, but...
As per forum #293892, it seems kind of silly to qualify Hoshino Ai (oshi no ko), a now 1928 post chartag from a popular series, because of hoshino_ai_(nature3111), a 7-post artist tag that before the aforementioned forum post hadn't had a new post in over 14 years. Given the discrepancy in popularity and the tags being different categories, I'd argue that the chance of confusion is extremely minimal and that there's no real value in having it be qualified.
