More realistic food

This data pack makes the food system in Minecraft more realistic! Eating food now takes significantly longer—on average, about 10 times longer. Different foods have different consumption rates: some are eaten faster, while others take longer. Also, some previously inedible items can now be eaten.

Furthermore, the entity limit has been changed: a single block can now hold a maximum of 5 entities instead of the standard 24, which helps improve balance and performance.
