Subject: [PATCH] Reduce nesting depth in gh22570 test to fix macOS ZTS timeout

The 100000-node tree could exceed the run-tests timeout on the macOS
ZTS runner. The 512K stack limit overflows well below 10000 nested
nodes, so reduce the depth to keep the test fast while still tripping
the serializer stack guard.
