Undyed shulker box can be put inside bundle

Unlike colored shulker boxes, the undyed versions can be put inside bundles, allowing for
what's essentially infinite inventory storage.

This is caused by an oversight in the bundle's "minecraft:storage_item" component. It bans "minecraft:shulker_box" from being put inside, but that doesn't cover the regular version, which has the "minecraft:undyed_shulker_box" ID.

Additionally, it'd be better to list every single variant manually instead of relying on outdated unified IDs.
