[Feature] Possibility to set a required silktouch level

[Tizooo]

hey, it would be nice if it would be possible to set a required silktouch level, my use case for this would be that i have a custom pickaxe with a custom texture and stuff and only with this one it should be possible to break spawners, this way we could make special pickaxes for breaking spawners.

my custom pickaxe /give command:
/minecraft:give Tizooo diamond_pickaxe[enchantments={levels:{silk_touch:10},show_in_tooltip:false},max_damage=10,custom_model_data=1]
