"Not enough <item name>" in Villagers' trades

Some items might not have plurals and if this were to be added many resource packs would have to be updated like for example if i made a resource pack that swapped diamond and coal and also changed the name and this would be fixed in an update it would say Not enough Coals or Not enough Diamond
