Cross references to old paths are gone in the latest CUDA Python docs

Although the modules are backwards compatible, the intersphinx mapping (objects.inv) only has the new module names in it.

Yeah seems to be the case

$ python -m sphinx.ext.intersphinx https://nvidia.github.io/cuda-python/objects.inv | grep cudaCpuDeviceId
    cuda.bindings.runtime.cudaCpuDeviceId                                            : module/runtime.html#cuda.bindings.runtime.cudaCpuDeviceId

and it seems to be a known limitation of Sphinx with aliased objects (maybe sphinx-doc/sphinx#10794 & sphinx-doc/sphinx#10151 are relevant).

We'll keep an eye on it, if it breaks too widely we'll need to figure out a workaround.

Let's wait and see how many projects rely on CUDA Python's objects.inv so that we can decide if this is a "won't fix"...
