Issue description

Mekanism ores don't generate in Terralith's custom biomes, only in vanilla biomes. Making ores like osmium rarer then Diamonds.

Steps to reproduce

1. Install the latest mekanism & Terralith mods
2. Create a new world
3. Search for mek ores in Terralith biomes

Minecraft version

1.19.2 (Latest)

Forge version

43.1.47

Mekanism version

10.3.5 (Latest)

Other relevant versions

I used worldedit to search areas within the different biomes for deepslate/stone based osmium ores. There was the rare occasion I would find mekanism ores in a Terralith biome chunk, but it would be only 1-5 ores total.

Terralith: v2.3.5

Terralith seems to be adding some entries to various biome tags that don't exist and this is cascading up to the top level making it so that the minecraft:is_overworld tag is empty. We use this tag for determining which biomes to add our ores to. A user on discord reproduced the terralith tag issue with just vanilla and terralith so I am confident it is on their end and not something we are doing.

Should be fixed in latest terralith version
