Docs: Growing with the web section

Section we removed because not enough thought has gone into this (the idea of behavior CSS).

Growing with the web

This project exists to fill in the gap between what's missing in the native web. This is in contrast to most headless ui libraries, which will build every ui pattern from scratch with a div.

Additionally, this approach includes future native APIs. Users of Qwik UI might use components that can gradually use native behavior. Eventually, these custom patterns won't need any JavaScript.

For example, Qwik UI's popover component uses the native Popover API on supported browsers. The Anchor API is also incrementally adoptable.

Long term, this improves maintenance, testing, and performance. We aim to work with the web to make things easy. While some components might need to mimic browser features, Qwik UI strives to avoid that when it becomes a detriment to the developer experience.
