Cannot create new space with HfApi.create_repo

[nateraw]

It seems the endpoint to create a HF space is looking for a sdk key/value pair in the json we pass up when making the request. We need to add an option to include SDK choice if repo_type ==. 'space'.

This snippet shows that it fails

from huggingface_hub import HfFolder, HfApi

name = 'deleteme-space-from-hf-hub'

token = HfFolder.get_token()
api = HfApi()
repo_url = api.create_repo(
    token=token,
    name=name,
    organization=None,
    repo_type='space',
    exist_ok=True
)
