CDNs updates page
CDN URLs are changed from time to time. Example in the past there was http://cdn-lfs.huggingface.co/ which is now cdn-lfs.hf.co.
It is causing many issues especially when we need to add URLs to whitelist.
It would be useful keep a page somewhere under huggingface.co updated with the available CDNs to allow users use it as a reference and get to know about the changes in advance.
