Describe the incorrect/future/missing documentation

CCCL documentation currently has the following structure:

• libcu++
• Thrust
• CUB
• Cuda Experimental

We have to embed Python documentation into this tree. To do that, we can consider adopting the following structure:

• CUDA C++
  • libcu++
  • Thrust
  • CUB
  • Cuda Experimental
• CUDA Python
  • cuda.cooperative

This structure requires authoring a new landing page with generic Core Libraries description that is not specific to C++ or Python. So the issue involves:

Tasks

Beta Give feedback

1. Upload Python docs as an artifact in GitHub actions
2. Restructure root toctree to include Python
3. Replace landing CCCL page with language-independent CCCL description
