Add proper boxes structure to minecraft:collision_box (1.21.130)

[ahnsunggwan45]

Bedrock 1.21.130 enforces a new schema for minecraft:collision_box that requires a boxes list defining min/max coordinates for collision shapes.
Customies previously generated only origin and size, which caused the client to crash shortly after joining.

This commit adds the required boxes: ListTag<CompoundTag> entry using local block coordinates (0 → size), ensuring the collision box matches the new format and preventing client-side crashes.

Only the collision_box component was modified; all existing behavior and APIs remain unchanged.

Using AxisAlignedBB for it would be better
or method similar to Digger etc..
a array of boxes
and limits too (-8, 0, -8) to (8, 24, 8) since going outside of bound will break it

Could you fix the formatting / indentation of the file, so we can see the diff more clearly?
