Trail Chamber Room Generation

Short description of the issue

There is one Trail Chamber room that generate incorrectly because areas that should contain Structure Void blocks are filled with air in the structure files, causing the room's edges to not generate with stone as intended.

Steps to reproduce the issue

1. Launch Minecraft Bedrock Edition.

2. Create a world with Trail Chambers.

3. Locate a Trail Chamber with this room. The edges that should be defined by stone are instead air because Structure Void blocks are missing.

4. Observe the generated room and check the areas where Structure Void blocks should be present.

Expected result

Trail Chamber rooms should generate with Structure Void blocks in the appropriate locations to preserve the intended room edges and boundaries. Basically make it blend to the enviroment.

Actual result

The areas that should contain Structure Void blocks are filled with air instead, causing the edges of the Trail Chamber room to be visible
