alias japanese_crested_ibis -> crested_ibis

create alias japanese_crested_ibis -> crested_ibis

Two existing tags for the same bird. https://en.wikipedia.org/wiki/Crested_ibis

I would recommend reversing the proposed alias and having japanese crested ibis remain the tag because almost all the posts in it are Kemono Friends related at present, it's unforeseeable whether that will change in the future, and japanese crested ibis (kemono friends) is an official name (see topic #13982). The two tags should match in my opinion.

I disagree with the reasoning but I'm fine with either way.

I think it's fine to follow wikipedia in this case.
