Taming any wolf also granted The Whole Pack and A Complete Catalogue: entity
predicates treated minecraft:components as always true, so every
tame_animal criterion of those advancements (one per wolf or cat variant)
matched the first animal tamed. EntityPredicate tests them with
DataComponentExactPredicate against what the entity reports through
Entity.get (Wolf.get(WOLF_VARIANT) and so on): mobs now report their variant
component (wolf, cat, frog, pig, cow, chicken, zombie nautilus) and the
predicate compares it, an absent component never matching.
Checked against the real EntityPredicate of every criterion of the variant
advancements on real entities of every variant by
tools/test_entity_components_parity.py.
