### Describe the issue

Shouldn't there be a `new` operator [here](https://github.com/isl-org/Open3D/blob/7a25f3dac4e1ec1b8a81592037ec5c6ffd34eca5/cpp/pybind/t/pipelines/registration/registration.cpp#L235)?

Sorry beforehand if I'm missing something, I don't really have any previous experience with `pybind11`...
