Add note about tauri integration to the books homepage? #129
Description
Currently it says that servoshell is the only way to use servo, but it might be worth mentioning that the tauri integration exists. Something like:
Work is still ongoing to make Servo consumable as a webview library, so for now, the easiest ways to use Servo are via _servoshell_, our [winit](https://crates.io/crates/winit)- and [egui](https://crates.io/crates/egui)-based example browser,
or via [tauri-runtime-verso](https://github.com/versotile-org/tauri-runtime-verso), a custom [Tauri](https://tauri.app/) runtime.
