(Bedrock Parity) 10% of dolphins should spawn as babies

This is already a feature in Bedrock Edition, but not Java Edition. I think it should be added.

NOTE: For some reason, "baby dolphins" is on the official "previously considered suggestions" list. It says baby dolphins won't be added, but they're already added in Bedrock Edition. Because of this, I'm assuming that the page means "no players breeding dolphins". If this is false, and baby dolphins are actually denied, then they should be removed from Bedrock Edition.
