Adds the aquatic Sunken Skeleton mob from Minecraft Dungeons. These skeletons spawn in biomes defined by the #wich:spawns_sunken_skeletons tag [default minecraft:warm_ocean, minecraft:lukewarm_ocean, and minecraft:deep_lukewarm_ocean].
When killed by a player, Sunken Skeletons have a chance to drop coral depending on their variant and more frequently with the Looting enchantment. When sheared by a player, they will drop coral and the coral will disappear from their heads. Sheared Sunken Skeletons will not drop coral when killed.
Skeletons fully submerged in water in one of the biomes defined by the #wich:skeletons_can_become_sunken tag [default the same as the #wich:spawns_sunken_skeletons tag] can also convert into Sunken Skeletons the same way they can convert into Strays in Powdered Snow. Sunken Skeletons' arrows are not slowed down by water.
