Added adventure/heart_transplanter and husbandry/place_dried_ghast_in_water
1.21.6 adds two new advancements, Heart Transplanter, and Stay Hydrated
Heart Transplanter: Place a Creaking Heart with the correct alignment between two Pale Oak Log blocks
Stay Hydrated: Place a Dried Ghast block into water
minecraft:nether/use_lodestone changed to minecraft:adventure/use_lodestone
This update changed the category of "Country Lode, Take Me Home" to Adventure because of the new crafting recipe using an iron ingot instead of a netherite ingot.
