[VMR] Rare Crate does not contain all unobtainable items

Minecraft Username:

Brief Description:
As of the 1.13 flattening, the Rare Crate no longer contains all of the unobtainable items. Because the Booklet counts items based on Spigot's Material enum, blocks and items that were previously all covered under an umbrella of data values are now separate items according to Minecraft and Spigot, thus requiring each and every one of these variants to be sold in order to count toward the Booklet (instead of one of many with separate data values).

This makes the Booklet Medal impossible to achieve in its current state.

Instructions:
Use the VMR Rare Crate.
Notice how the crate only contains 16 of the required 68 unobtainable items.

How many times did you recreate this?:
N/A

Result:
Rare Crate contains 16 items.

Expected Result:
Rare Crate contains 68 items.

Evidence:
I've listed out the new list of Spigot Material IDs of the unobtainable items of Minecraft.
This list was compiled by taking the enum values of org.bukkit.Material and removing any Material IDs that did not have an item form. These were then further sorted to items that were unobtainable by any means in Survival Minecraft.
