The tree in the "entrance_1" room of trial chambers no longer represents a naturally grown oak tree

Bedrock Edition repost of MC-271167.

Previously, the tree in the "entrance_1" room (aka entrance room) of trial chambers represents a naturally grown oak tree. However, this was changed in one of the 1.21 preview versions.

Interestingly though, MC-271137 seems does not happen in Bedrock Edition.

Steps to Reproduce:

1. Find a trial chambers, and locate its "entrance_1" room.
2. Take a note at the appearance of the tree.
3. Now do the same thing in 1.20.80.
4. Compare them.

Observed Results:
The tree no longer represents a naturally grown oak tree.

Expected Results:
The tree would still represent a naturally grown oak tree.
