Rename "western"

BUR #7200 has been approved by @nonamethanks.

create alias western -> cowboy_western

Simple change to prevent any future mistagging.

I agree but prefer western_(film_genre)

Why not wild_western?

The tag can also apply to tame westerns so I don't agree.

sorry, but this name is dumb

BUR #11544 has been approved by @nonamethanks.

remove implication cowboy -> cowboy_western

odd oldbooru reasoning (topic #6884)

Nowadays it would be like having a wizard -> fantasy implication
