Please add support for PEP-691: support JSON for the `/simple` API endpoint

[Jeff Widman]

It'd be great to see support for https://peps.python.org/pep-0691/ added at some point.

That way tools like could start fetching the /simple endpoint via JSON rather than parsing static HTML.

Thanks a lot for pointing to this @jeffwidman! I'll study the PEP and try to see if there's a fast solution feasible. If anyone's interested in going ahead already - any help/PRs are of course always welcome 🙏 😊
