Steak (in Java Edition) is called Cooked Beef in Bedrock Edition.

The Namespaced ID is cooked_beef.

In the language file of Bedrock Edition, there are two strings related to it:

item.steak.name=Steak

item.cooked_beef.name=Cooked Beef

And only the second one is in use.

But as we all know, only one string in the language file of the Java Edition is related to it:

"item.minecraft.cooked_beef": "Steak"

So why the two versions have different names, and why there's an unused string in Bedrock Edition? Why in the Translation Key of Java Edition is also called "cooked beef"?
