chore: replace broken hope-ui link with kobalte in readme

[esauri]

Summary

Currently component libraries links out to https://hope-ui.com/ which no longer works. Looking at the hope-ui repo, we find a working link (https://hope-ui.netlify.app/).

However, this library is deprecated and points to https://pigment.kobalte.dev as a successor. I've opted to instead link to https://kobalte.dev as it has more documented components than the pigment site.

Could also link to https://www.solidjs.com/ecosystem#ui if that is preferred.

How did you test this change?

I clicked some links.
