Wandering Trader doesn't sell pointed dripstone, small dripleaf, rooted dirt, and moss block

The wandering trader doesn't sell pointed dripstone, small dripleaf, rooted dirt and moss block. This isn't in parity in Java and it would be nice to have a way to obtain these items while the biome isn't generating yet.

Step to Reproduce
1. Find/spawn a lot of wandering trader
2. Check to see if they sell those things.
---> They don't sell pointed dripstone, small dripleaf, rooted dirt and moss block.
