In this part of the course, HUGGINGFACE_API_TOKEN is an error?
I'm a beginner on hf so I may be wrong.
HF_TOKEN was used sooner in the course but HUGGINGFACE_API_TOKEN is used in the Complete Example section.
Also, if HF_TOKEN is the correct one, it can be useful to precise that you don't need to worry about how to set that variable in hf space since it is done automatically (I was a little worried about that).
