PWA (progressive web app) 的清单文件
The manifest file can have any name, but is commonly named manifest.json and served from the root (your website's top-level directory). The specification suggests the extension should be .webmanifest, but browsers also support .json extensions, which may be easier for developers to understand.
可以看见包整体有name, icon, description，每个快捷方式也有自己的name, icon, description。
另外，还有screenshot, 用于兜售这个应用的界面。
