MCPE-189647Chunks that were corrupted before 1.18 are missing anything below y 0
When an old world (like from windows 10 beta 0.15>) was loaded before the cave updates, these chunks are removed. But if these chunks are updated, the blocks below y=0 are still missing. This shouldn't happen and instead generate the caves below y=0.
Steps to Reproduce:
1. Take any old world created and last loaded before 0.15.0
2. If the world is loaded in a newer version like 1.16 before the cave update, the alpha chunks will be deleted.
3. Load world in newer/newest version after 1.18
Observed Results:
After updating the world, there are no blocks generated below y=0 from the caves and cliffs update.
Expected Results:
There should be new blocks generated below y=0 from the caves update in the missing chunk.
Note: The Chunks that aren't voided weren't loaded in alpha. These were generated in 1.16 or 1.20.

Please attach the world you are using to reproduce the issue.
The attached world simply has a lot of voided chunks, but I do not see any chunks that are generated normally above 0 missing the below-0 cave layers.
Void chunks from pre-1.18 worlds not generating anything below 0 is intended per
MC-241979.
