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

Thought of when testing https://github.com/huggingface/huggingface.js/pull/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
