Infinitas Shamir: Update to 1.20 and leftover fixes

[EpyonProjects]

• Actually works in 1.20, after including the required location tags
• Addresses SneakingSpider's last mentioned issue regarding milk/cows
  • Turns out milk uses player_interacted_with_entity, not filled_bucket
• Addresses rx's concern about the powder snow toggle
  • It is now off by default
• Updates the bucket shamir nbt in init
  • As a result, this autoupdates pre-existing Infinitas buckets after use

Works as advertised, therefore it is ready to be merged.

A future PR should make it so that the lava toggle is loaded from the gamerule once upon first install. The same goes for a water toggle that should be added:

execute unless score $water_infinitas gm4_ml_data matches 0..1 store result score $water_infinitas gm4_ml_data run gamerule waterSourceConversion
execute unless score $lava_infinitas gm4_ml_data matches 0..1 store result score $lava_infinitas gm4_ml_data run gamerule lavaSourceConversion

At that point, only Milk wouldn't have a toggle so I suggest also adding one for milk.
