Charm Drag-And-Drop shulker fix

This small mod fixes the operation of the shulker drag-and-drop module in the Charm modification.

The standard version of the module always uses the container size of a regular shulker box, even if you use modified versions with increased capacity. This particularly applies to shulkers from the Reinforced Shulkers mod, which have a larger volume compared to vanilla counterparts.

This fix allows reinforced shulkers to be used to their full capacity, ensuring proper operation with enlarged containers through the drag-and-drop function in Charm.
