Make all min/max values in predicates able to reference storage values

The Number Provider being able to access storage values since 24w12a is really nice. Being able to change values used for comparison is very powerful. However there are some instances where predicates and loot_tables cannot use these, such as some min/max values. An example is checking the amplifier level if an entity's effect. The values for min and max must be hard coded, but it would be amazing if instead we could do something like min = 0, max = storage value.
