[MC-307803] The game crashes when a sulfur cube with an archetype that has `explosion_fuse` set to a value lower than 4 is primed by an explosion

explosion_fuse of sulfur cube archetype is not restricted to be positive, and values lower than 4 causes crash IllegalArgumentException("Bound must be positive") since it will be passed to PrimedTnt.getRandomShortFuse(), eventually to random.nextInt(fuse/4) without validation.

Confirmed and attached a crash report and simple repro pack.

This only occurs when the sulfur cube is set off by another explosion, not when it is ignited manually.

How to reproduce

Install the attached data pack.
Spawn a sulfur cube
Feed it an apple
/summon tnt
