The same report as MCPE-182290 but now for light blocks.

When the light_block block ID was flattened in 1.21.20, its new split IDs were not assigned a sound property.

This causes them to use an incorrect pitch for the breaking sound that differs from other blocks assigned the stone sound set.

To Reproduce

1. Open the blocks.json file from the Bedrock Edition 1.21.20 resources.
2. Find the light_block_0 entry.
3. Notice all the light blocks are missing a "sound" property.

Expected Result

Light blocks are assigned the "stone" sound set. They sound identical to other stone blocks like Java Edition.

Observed Result

Light blocks are not assigned any sound set, causing them to fall back to the "normal" set. This makes them sound different from other stone blocks.
