Oak saplings can appear in chests in savanna villages

The bug

The loot table minecraft:chests/village/village_cartographer contains oak saplings, which can appear in any village. In this case, it does not make sense for oak saplings to be found in a savanna village.

How to reproduce

Command for testing:

/setblock ~ ~ ~ chest{LootTable:"minecraft:chests/village/village_cartographer"}
