minecraft:storage_item is an item component: it goes in the components object of a custom item. Lets the item carry other items inside it, like a bundle. Other components, such as minecraft:bundle_interaction, use this storage.
It is experimental: it only works in worlds with the matching experiment turned on, and it may change in future versions.
