biome_modifier: forge:add_spawns

[Zacomat]

Could someone please explain the 'weight' parameter in the 'biome_modifier/my_mob.json' file?

Based on my experiments, I've observed the following:

Weight 5: Very rare

Weight 10: Rare

Weight 15: Uncommon

Weight 20: Common

Weight 25: Very common

These results were obtained from exploration in caves and on the surface using the following file:

{ 
	"type": "forge:add_spawns",
	"biomes": "#minecraft:is_overworld",
	"spawners": { 
		"type": "exmplemod:my_mob",
		"weight":15,
		"minCount": 1,
		"maxCount": 1
	}
}
