⚙️ 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.
