Allow Drowned Trading Trident with Nautilus Shell

Drowned zombies loves both tridents and nautilus shells but what if we pay them for the trident.
Would this break the game? No. Players don't need much trident for combat, it was not used that much after all, unless in bedrock it is used as a trident farm.
Anyways, let us allow Mojang to paste some code from the Piglins.
Now, Drowned Zombies can accept items for trade. My suggested currency is nautilus shell.
If you trade with nautilus shell, you are guaranteed to have a trident 61% of the time for one nautilus shell if the drowned is holding a trident. If not, the drowned will have no tridents dropped but instead keep the nautilus shell for free so don't give it to drowned_zombies_without_trident. The other 39% chance will make the drowned zombie drop nothing.
