## Current Behavior
There is a migration that always adds `sass-embedded` for Rspack and
Webpack for 20.5
## Expected Behavior
`sass-embedded` is already a dependency of Rspack and Webpack and
therefore does not need to be added to users package.json - especially
as they may not be using it.
## Current Behavior
Webpack and Rspack currently use `sass` and its Legacy API with
`sass-loader`.
There is also no method to pass stylePreprocessorOptions other than
`includePaths` to the loaders.
## Expected Behavior
Switch to using `modern-compiler` api to remove deprecation warnings and
improve build performance.
Allow users to choose between `sass` and `sass-embedded` for sass
compiler implementation.
Expand the `stylePreprocesserOptions` interface to accept
`includePaths`, `sassOptions` and `lessOptions` that will be passed to
the appropriate loader.
