…es in 0.26.0 (#22508)

### Description
Pin huggingface_hub to 0.25.2 due to breaking changes in 0.26.0.



### Motivation and Context
We depend on `diffusers==0.28.0`, which [depends
on](https://github.com/huggingface/diffusers/blob/v0.28.0-release/setup.py#L104)
`huggingface_hub>=0.20.2`. There are breaking changes with the latest
huggingface_hub 0.26.0 release that break our Big Models pipeline:
[Release v0.26.0: Multi-tokens support, conversational VLMs and quality
of life improvements ·
huggingface/huggingface_hub](https://github.com/huggingface/huggingface_hub/releases/tag/v0.26.0)

Specifically, the breaking changes to `cached_download()` cause our
pipeline to fail.
