Describe the bug:
Lava lakes sometimes fail to generate, with lava-free caves generating all the way down to bedrock in some cases.

Lava lakes, when they do generate, seem to generate 1 block lower than they do in vanilla, at Y=-56 instead of Y=-55 like in vanilla.

To Reproduce:
Steps to reproduce the behavior. Format it as a numbered list of steps.

1. Install Spelunkery and its Moonlight lib for Forge 1.20.1 as outlined above.
2. Boot up the game and start a new world (Default world type, Creative mode, Hard).
3. Navigate to lava lake level (~Y=-55) in the overworld and roam around. Will likely be easier in Spectator mode.

Expected behavior:
Lava lakes should consistently spawn at Y levels -55 and below in the overworld.

All of the testing was done with Prism Launcher.
