Details

The type of additionalData function of sass plugin is

type Callback<T> = (loaderContext: Webpack.loader.LoaderContext) => T;

However, there is supposed to be a content argument:

// This is what the type is supposed to be
type Callback<T> = (content: string, loaderContext: Webpack.loader.LoaderContext) => T;

Which one is right? I can do a PR if you confirm that this is just a type error.
If this is not the type error, how can I get the content and manipulate it?

Reproduce Steps

1. try to use the content argument from the additionalData function of pluginSass.
2. get a slap from Typescript, because it's not a string type.
