Device properties docs are broken

[leofang]

@kkraus14 pointed out that the attributes of the DeviceProperties in the docs are somehow lost: https://nvidia.github.io/cuda-python/cuda-core/latest/generated/cuda.core.experimental._device.DeviceProperties.html
Compare this to what we had in v0.3.2 (before switching to the nvidia-sphinx-theme):
https://nvidia.github.io/cuda-python/cuda-core/0.3.2/generated/cuda.core.experimental._device.DeviceProperties.html

#1100 likely has the same root cause, that the new Sphinx theme probably made a few incompatible assumptions.
