Showcase Removal Notice

Hello friends of Tauri,
With the upcoming v1 release and accompanying overhaul of the https://tauri.studio website, we will be removing the showcase section in favor of [**Awesome Tauri**](https://github.com/tauri-apps/awesome-tauri).
If you want to keep your project featured, please submit it to that list instead, but please note the rules for submissions have changed.

Thank you for all your support in getting Tauri to this point!

Jonas,
the Tauri team
