This adds support to show the icons provided in the item_model item data component. (Requries 1.21.9+) The plugin calculates the texture path from the item_model value e.g. if the item_model component is your_plugin:some_custom_item then the client will look for a texture in your_plugin/textures/item/some_custom_item when displaying the message. (This is compatible with most vanilla item models too) A new config option show-custom-item-models (defaults to true) was added to disable the showing of the custom item models as icons in case your setup does not correctly resolve them or you haven't adjsuted the texture locations in your resource pack to work with this yet.
Fixed an issue where the icons of leaves where gray instead of green.
