⚙️ Datapack creation

Components on (an) item(s) can be changed by adding an entry under <namespace>:item_components/<path>.json.
Entries have 3 fields, all optional:

• parents: an ID or an array of IDs
  • The entries to inherit. Note that only the parent's parents and parent's components are inherited, not the parent's targets.
• targets: an item ID, an item tag suffixed with '#' or an array of item IDs
  • The items to apply the component changes to.
• components: a component changes object
  • The component changes to apply to the items.
