Invalid input data for `ImageToTextOutput`: Expected a single instance, but got a list.

Describe the bug

When inferencing with image_to_text() method, it reports a value error: ValueError: Invalid input data for <class 'huggingface_hub.inference._generated.types.image_to_text.ImageToTextOutput'>. Expected a single instance, but got a list.

It looks like the post response need to be parsed as a list:

raw_response = client.post(data=image_data, task="image-to-text")
ImageToTextOutput.parse_obj_as_list(raw_response)[0].generated_text

I verified the above code could work as expected.
