Most temples (at least of the types "witch hut", "desert temple", "jungle temple", and "igloo") are not being generated when the chunks containing them are generated. Experiments using 1.18.1 show they were being generated at that time, but they no longer are.

Steps to Reproduce:
Note: After navigating to a location, you can use /locate temple to verify that a temple is supposed to generate there.

1. In 1.18.10, create a new world with seed 5522698.
2. Navigate to -280, 312. Verify that there is no desert temple there,
3. Navigate to 312, 72. Verify that there is no desert temple there,
4. Navigate to -264, -392. Verify that there is no witch hut there.
5. Navigate to 216, -280. Verify that there is no witch hut there.

Expected Results:
Most temples generate where expected, though a small percentage may be canceled because of terrain incompatibility, conflict with other structures, etc.

Observed Results:
The number of missing temples within 1000-2000 blocks of spawn is larger than expected.

Additional Information:
A test using a different seed with a more extensive list of missing temples can be found below in a comment. In this test, almost all of the temples are missing.

Original description:
When using the /locate temple there is frequently no structure at the location given. In particular the desert temple, jungle temple and witch hut structures often don't generate.

Steps to Reproduce:

1. Load a new world with the seed 5522698
2. /tp -280 100 312
3. /locate temple
4. Note that the coordinates are the same and no structure exists
5. /tp 312 100 72
6. /locate temple
7. Note that the coordinates are the same and no structure exists
8. /tp -264 100 -392
9. /locate temple
10. Note that the coordinates are the same and no structure exists
11. /tp 216 100 -280
12. /locate temple
13. Note that the coordinates are the same and no structure exists

Observed Results:
At all 4 locations the structure didn't generate where the locate command says it should.

Expected Results:
Structures should exist at the locations the /locate command outputs

Notes:
This issue seems to have been introduced at some point between 1.18.0.24 and 1.18.10.20. I loaded up a seed which I had previously noted had a witch hut at a specific location and its not there in 1.18.10.20.
