Improvement suggestion for the README

[lmartinez2001]

In the Gradio demo section, it would be relevant to specify that one must login to hugging face before running the demo.
For instance specifying that one must run the command huggingface-cli login should be informative enough.

Hi,

I think the models hosted on HuggingFace are public, so there is no need to login, right?

Best,
Runsen
