Baby Aquatic Mob Buckets

Baby aquatic mobs should be bucketable. (Squid, Dolphin, Turtle, and Nautilus).
- Baby squids and dolphins can only be found, not bred. Players should be able to bucket these rare baby mobs so that they can be moved from where you find them to a safe location.
- Axolotl babies can already be bucketed; they are larger than baby turtles, so baby turtles should also be able to fit in a bucket.
- Baby Nautilus are no larger than adult axolotl (which can be carried in a bucket), and as such should also be eligible for bucket rides.
