Update Minecraft GUI item selection options to include newer items

I’ve noticed that Minecraft items introduced after version 1.13 are missing from the Minecraft GUI item selection options. One example is armor trims, which would be great to use for cosmetic packages.

It would be fantastic if the list of available GUI items could be updated to include items from more recent versions of the game. Even better would be a long-term solution to help keep this list up to date automatically or with minimal effort.
