Pepijn 7241f029c6 docs(streaming): A100/H100 NVDEC cannot decode AV1 — correct guidance ...

NVIDIA's decode support matrix: the compute GPUs A100 (GA100) and H100 (GH100) have no
AV1 NVDEC decoder; only Ada (L4/L40/RTX40) and some Ampere (A10/A40/A16) do. So on
A100/H100 nodes, AV1 datasets must be decoded on CPU or re-encoded to H.265/H.264 — no
torchcodec build enables cuda AV1 decode there. Also distinguish that error from
"Unsupported device: cuda (variant: ffmpeg)", which is a torchcodec-built-without-CUDA
issue. Update diagnose_decode.py message + benchmark README accordingly.
