[issue36880] Returning None from a callback with restype py_object decrements None's refcount too much

[anthony shaw]

If you can write a test similar to the AnotherLeak.test_callback test case, and commit that first.

It will show in the CI/CD log as failed and verify the issue (incase it comes up in PR review)

Then add another commit with the patch itself and we should see the CI/CD pass.
