Display Node

• Add CustomName and CustomNameVisible

Vanilla Item Display Node

• Enable users to input a custom ItemStack component string
  (Validation would be a nice-to-have but is low priority as far as plugin mode is concerned)

  wooden_pickaxe[custom_model_data=12,enchantments={levels:{"minecraft:respiration":1}},tool={default_mining_speed:12,damage_per_block:1}]

• Add item_display property
  (ideally, include an editor preview for enhanced user experience)
  

• Rename from "Vanilla Item Display" to "Item Display" to reflect these changes

Vanilla Block Display Node

• For consistency, shorten "Vanilla Block Display" to "Block Display”
