Suggestion to add WebApp manifest in reactjs.org

If we allow users to Add to homescreen the https://reactjs.org I think it would be helpful for people who want to have react docs on their homescreen and it would allow them to easily access the docs anytime they want.
Along with this we can even set the theme color for URL bar.

we can add gatsby-plugin-manifest to achieve this.

Edit: If you guys are planning to implment it I would love to work on this. It would be my first contribution here

未指定檔案或測試。首先查看 react.dev 的 Gatsby 設定和 gatsby-plugin-manifest 文件；完成標準是文件網站支援將應用程式新增至主畫面，並為 URL 列設定主題色。
