Fix/adjust diffusion: restore huggingface_hub line to no-torch-runtime for PR #5754

Browse source 
Round 34 P1: R33 removed the `huggingface_hub>=1.3.0,<2.0` line
entirely when the right revert was to restore the pre-PR
`huggingface_hub>=0.34.0` floor. install.sh --no-torch installs
this requirements file with --no-deps and does NOT install
studio.txt afterward, so without an explicit Hub line a no-torch
Studio install ends with no huggingface_hub at all and the new
diffusion + chat GGUF paths fail at import with
ModuleNotFoundError: huggingface_hub.

Restores the pre-PR floor and documents both the round-26 walk-back
and the round-34 reason the package line stays.
