Lava lake decorator config is unused

The lava_lake decorator uses a chance configuration, but it never uses this chance.

Code snippet uses Mojang mappings, showing that the LakeLavaPlacementDecorator doesn't use the config.

protected int count(Random random, ChanceDecoratorConfiguration config, BlockPos blockPos) {
    return blockPos.getY() < 63 || random.nextInt(10) == 0;
}

When using this decorator the chance is required.

    "config": {
        "chance": 80
    }
}
