Complete removal of /info entity, it's correspondent carpet and two small changes (#1047)

* Remove no longer needed language packet mixin

* Make StringArgument properly return a StringArgument supplier, so `string` isn't `term`

Fixes gnembon/fabric-carpet#1044

* Complete removal of `/info entity` and it's correspondent carpet

Resolves gnembon/fabric-carpet#1033

* Remove yet another no longer needed mixin
