Trial chambers generation is slightly different

Trial chambers generation is slightly different in 1.21.40.20 when compared to previous versions. This is not mentioned in the changelog, as such I assume it's a bug.

Seed: 3521727207246953729
Coordinates 1: 727 -5 118
Coordinates 2: 749 -10 164

Steps to Reproduce:

1. Create a new world using the given seed.
2. Teleport to one of the given coordinates.
3. Notice how it's generated.
4. Repeat the steps above in 1.21.23.
5. Compare the results.

Observed Results:
In coordinates 1, a "slanted" room is generated instead of a "chamber_2" room. In coordinates 2, the "chamber_2" room is generated with a different configuration. There are also some smaller differences, such as barrels, candles, decorated pots, dispenser traps, and flower pots.

Expected Results:
Trial chambers generation would stay the same.

Notes:
Coordinates 2 needs Spectator mode to access.
