Torchaudio is unavailable for cu132 torch

> We generally recommend using the latest major version of pytorch with the latest cuda version unless it is less than 2 weeks old.

Torch 2.12.0 released 20d ago, with cu126/130/132 backend.
For cu126/cu130, torchaudio 2.11.0 is compatiable with torch>=2.11.0 so there's no problem.
However for the latest cuda version cu132 there's no stable torchaudio wheel available, and I tried to use torchaudio nightly wheel but end up with dll mismatch.
So I guess either manual install doc should be updated, or ComfyUI should change torchaudio to optional deps?

Reproduce the installation with the cu132 PyTorch build and the available torchaudio wheels, then inspect ComfyUI's manual installation guidance and torchaudio dependency handling. Confirm whether the supported outcome should be updated documentation or making torchaudio optional, and consider the issue resolved when cu132 users have a documented working path or no longer require the unavailable dependency.
