Add Qwik.dev Docs

# Feature request

## Summary

[Qwik](https://qwik.dev) is a younger JS framework that has been growing rapidly in popularity and is built by Builder.io. It would be nice to see docs for it in DevDocs.

- https://qwik.dev
- https://github.com/BuilderIO/qwik

Start by reviewing the Qwik documentation at qwik.dev and the BuilderIO/qwik repository to understand the source material and scope. Then read the DevDocs contribution guidance and identify the existing documentation integration pattern to follow. Done means Qwik documentation is available in DevDocs with the expected navigation and content.
