Alias aotsuyu , aojiru_(shiru_ka_yo), ao_(6639) -> aojiroi

BUR #124 has been approved by @fredgido.

create alias aotsuyu -> aojiroi
create alias aojiru_(shiru_ka_yo) -> aojiroi
create alias ao_(6639) -> aojiroi

All of them are the same artist on different social media platforms.

I ran through all of the ao_(6639) posts while I was adding the model name from the metadata (please check metadata, the model names are listed right there), but I'd prefer if the aojiru_(shiru_ka_yo) were batch changed.

Don't know if the alias is still necessary, but I updated all the posts from aojiru_(shiru_ka_yo) and ao_(6639) to the aojiroi tag.

The bulk update request #124 (forum #959) has been approved by @fredgido.
