Alias dragon_horn

BUR #55603 has been rejected.

create alias dragon_horn -> dragon_horns

I cleared this out earlier, it primarily had a mixture of Arknights: Endfield posts with two horns and Blue Archive Posts with single horns, either way this doesn't need to exist when you can find them with dragon_horns single_horn.

Should just be updated and deprecated in my opinion. Dargon_horn already brings up dragon_horns so it's not a helpful alias.

deprecate dragon_horn

As above.

Just want to say that, in my ignorance, I ended up deprecating dragon horn... so if the alias BUR gets approved, whoever approves it has to do a quick undeprecation BUR as well.
