Prepare for CUDA Python new documentation layout

rmm/python/rmm/docs/conf.py

Line 200 in 1024a12

"cuda-python": ("https://nvidia.github.io/cuda-python/", None),

Once this PR NVIDIA/cuda-python#183 is merged I expect that RMM doc build will break again.

Based on this search team RMM is the only consumer of CUDA Python's objects.inv, so wanted to inform you in advance 🙂

Our docs has been rebuilt last Friday, so the new URL should be replaced to https://nvidia.github.io/cuda-python/cuda-bindings/. This file can be inspected:

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

(If https://nvidia.github.io/cuda-python/cuda-bindings/ does not work for any reason, I would like to know and we should also try https://nvidia.github.io/cuda-python/cuda-bindings/latest...)
