Describe the bug

Using ItemStack#of during recipe registration throws exception which makes it impossible to register any recipe.

Code to reproduce:

@Listener
public void registerRecipies(final RegisterRegistryValueEvent.EngineScoped<Server> event) {
	event.registry(RegistryTypes.RECIPE, step -> {
		ItemStack.of(ItemTypes.COBBLESTONE);
	});
}

This is one of the breaking changes in vanilla, you no longer can access the ItemStack in any stage of the registry loading, the server has to be fully loaded.

Thanks for logging, we need to figure out what to do with this.

Is this where we'd be using ItemStackLike (which we can mark as an ItemStackTemplate under the hood)?
