huggingface embeddings test fails

[eliben]

Trying to see if I can refactor the embeddings for huggingface for #379, but the test currently fails when I set an API token:

Running from the embeddings/huggingface directory:

$ HUGGINGFACEHUB_API_TOKEN=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 go test -v .
=== RUN   TestHuggingfaceEmbeddings
=== PAUSE TestHuggingfaceEmbeddings
=== CONT  TestHuggingfaceEmbeddings
    huggingface_test.go:22: 
        	Error Trace:	langchaingo/embeddings/huggingface/huggingface_test.go:22
        	Error:      	Received unexpected error:

@zivkovicn and @tmc any ideas?

@eliben didn't check the code I'm afk atm, but sometimes we get 503 from the huggingface hub b/c there are no available instances for free accounts. https://huggingface.co/docs/api-inference/faq#rate-limits not sure if it is related, but there is a possiblity.
