[MC-184634] Worldgen setting with seed 0 is interpreted as an ASCII code

The bug

Setting the worldgen_settings.json file to have "seed": 0 causes the game to interpret it as ASCII and automatically set the seed to literal 48 instead of a random seed upon generation.

Can confirm for 1.16.1

This really needs to be fixed, it makes it impossible to generate random seeds for a dimension datapack. It kind of ruins all datapacks that change the biome generation or make a new dimension.

Confirmed for 1.17.1

The systems have changed in upcoming versions making this repro case no longer valid. Please test if this is still an issue in any snapshot for Minecraft 1.19 (or later).
