pack: v0.31.1 — restore Capsid recipe override (Shattered Carver)

I removed this datapack override in v0.31.0 on the (incorrect)
assumption that Item Obliterator would also handle Alex's Mobs'
custom capsid_recipes recipe type. It doesn't -- Item Obliterator
intercepts vanilla and some common modded recipes, but the Capsid
uses its own SimpleJsonResourceReloadListener bound to the
"capsid_recipes" folder, and that listener still loaded the
default shipped recipe.

The visible bug: a player could put a regular Dimensional Carver
into a Capsid -- the recipe matched, the Dimensional Carver was
consumed, and the Capsid spat out a Shattered Dimensional Carver.
Item Obliterator then refused the pickup. Net result:
  - Player loses their hard-earned regular Carver
  - Player can never pick up the Shattered one
  - World has an unrecoverable floating item entity

Restore the override at:
  pack/overrides/world/datapacks/bns-fuel/data/alexsmobs/
    capsid_recipes/shattered_dimensional_carver.json

This swaps the recipe's input from `alexsmobs:dimensional_carver` to
`minecraft:barrier`, which is unobtainable in survival. The recipe
loads cleanly but can never match. The Capsid transformation for
the Shattered Carver effectively no longer exists.

Item Obliterator still handles the JEI / creative tab / inventory /
trade removal -- both layers complement each other.
