deprecate alternate_body_size & create fatter_than_canon

Should we also have alternate body size (skinnier) for thinner than canon?

BUR #58691 has been approved by @nonamethanks.

create alias alternate_body_size_(skinnier) -> thinner_than_canon
create alias skinnier_than_canon -> thinner_than_canon

Sure.

remove alias alternate_height_size_(taller) -> taller_than_canon
remove alias alternate_height_size_(shorter) -> shorter_than_canon
create alias alternate_height_(taller) -> taller_than_canon
create alias alternate_height_(shorter) -> shorter_than_canon

Grammar improvement.

Woops, I was doing too many things at once yesterday.

BUR #58724 has been approved by @nonamethanks.

create alias alternate_body_size_(taller) -> taller_than_canon
create alias alternate_body_size_(shorter) -> shorter_than_canon

Doing these as well, so that alternate_body_size suggests all the tags that used to be lumped in this.
