Fix broken links in NPM documentation

[miabrahams]

Link to Github pages for JS Framework Benchmark and hope-ui

Summary

Hello! I was checking out Solid on npmjs.com and noticed a broken link to the performance benchmark. I clicked through the rest of the links in README.md and found hope-ui.com had also been taken down. I replaced the benchmark link with a github.io site that was used elsewhere and the hope-ui link to the Github repo.

How did you test this change?

I opened the VS Code preview and clicked the updated links.
