/place Command-Generated Trail Ruins Missing Suspicious Sand/Gravel

When using the /place structure minecraft:trail_ruins command to generate trail ruins, the structure does not contain suspicious sand or gravel blocks. Normally, naturally generated trail ruins include these blocks as part of their lootable components.

Steps to Reproduce:

1. Use the command /place structure minecraft:trail_ruins to spawn trail ruins.

2. Inspect the generated structure for suspicious sand or gravel blocks.

Observed Result:
The placed trail ruins structure lacks suspicious sand/gravel blocks, unlike naturally spawning ruins.

Expected Result:
The /place command should generate trail ruins identical to natural ones, including suspicious sand/gravel blocks with loot tables.
