Add Open-Sora as library (#1288)

We added `library_name: open-sora` here:
https://huggingface.co/hpcai-tech/Open-Sora-v2, hence this PR ensures
download stats work for them.

cc @zhengzangw let me know whether I also need to add a custom code
snippet, which will show up for users as a "Use this model" button at
the top right, see https://huggingface.co/jameslahm/yolov10x as an
example.
