Creating Your First Item: "NullPointerException: Item id not set" in Minecraft 1.21.2 and onward

[valentinegb]

Following the Creating Your First Item guide as it is now, results in the following error:

NullPointerException: Item id not set

According to the blog post Fabric for Minecraft 1.21.2, this can be resolved by manually setting registry keys. Here's the example in the blog post:

Identifier id = Identifier.of("mymod", "test_item");
RegistryKey<Item> key = RegistryKey.of(RegistryKeys.ITEM, id);

Item.Settings settings = new Item.Settings()
    // If your item is based on a block
    .useBlockPrefixedTranslationKey()
    .registryKey(key);

Registry.register(Registries.ITEM, key, new Item(settings));

The current guide is for Minecraft 1.21.1, please track the update to 1.21.3 in #206

Should I close this issue too?
