Items in the Useable Items Panel of Beacons Use Wrong Textures

The items displayed on the usable items panel in the beacon screen use the wrong images in the 1.16.100.50 beta.

Expected images:

Netherite, Emerald, Diamond, Gold, Iron

Actual images:

Nothing, Ender Pearl, Raw Cod, Tropical Fish, Raw Salmon

This bug may be related to the technical item changes introduced in 1.16.100.50 since these images are rendered as part of the item renderer using an #item_id_aux value in the UI file.
