Ore: Nether Gold

Added chance of Piglin Trading to drop Nether Gold Ore (Weight: 5).

This does not change the total chance of getting any of the other items.
Nether Brick has had its weight halved compensate for this item and Nether Quartz Ore. Doubled drop count of the bricks to compensate.

Note: Piglins will try to pick this up after throwing it.
