CDN: Reference unbundled/unminified files directly instead of base esm/jsdeliver links?

[coyotte508]

Thought of when testing #682

Currently in the README.md we add example CDNs including from esm.hs or jsDelivr, but they bundle/minify the files.

We should maybe link directly to https://cdn.jsdelivr.net/npm/@huggingface/hub/dist/browser/index.mjs for example, which is the unminified/unbundled file
