Sulfur cubes trigger block update when hitting activated sulfur (minigames)

   Some minigames could require detecting if a sulfur cube hit a certain area. However, certain games like volleyball share room with players and other entities, meaning normal detection methods such as tripwires, sculk sensors and redstone ore won't work as well on detecting only the sulfur cubes.

   My suggestion is to make activated sulfur (or a specif block) trigger an observer in a similar to redstone ore when hit by a sulfur cube only.
   That would allow more complex minigames such as baseball, volleyball and others to not suffer from player inteference on detection.
