Alias for Sophie from Howl's moving castle

BUR #41762 has been approved by @nonamethanks.

create alias sophie_(howl_no_ugoku_shiro) -> sophie_hatter

Currently it looks like there are two separate tags being used for the same character, Sophie from Howl's Moving Castle.

And now that I've looked into it a bit more closely, we also have howl_(howl_no_ugoku_shiro) and wizard_howl as well.

Edit: I'm not quite sure how to go with this one. I believe Howl has two different full names. There's Howl Pendragon, his preferred alias, and his birth name Howell Jenkins. Should both of the existing tags be aliased to one of those?

BUR #42298 has been approved by @nonamethanks.

create alias howl_(howl_no_ugoku_shiro) -> howl_pendragon
rename wizard_howl -> howl_pendragon

As above, unifying these tags.
