Missing InjectManifest documentation

Hi there,

I was looking into the InjectManifest Plugin Documentation to clarify some issues I am facing within an existing Workbox SW implementation in an application.

I found the following URL with a basic example of InjectManifest Plugin: https://developer.chrome.com/docs/workbox/modules/workbox-webpack-plugin#injectmanifest_plugin

However, the reference documentation link in the above page redirects to here: https://developer.chrome.com/docs/workbox/modules/workbox-build#type-WebpackInjectManifestOptions

Above are the WebpackInjectManifestOptions for workbox-build, NOT workbox-webpack-plugin. The options here are clearly different to those shown in the example. Please fix this so that we are aware of the actual options available for workbox-webpack-plugin.
