Link for SplitCompatApplication is broken

In section 4: [4. Add support for Split Install API in your app](https://developer.android.com/codelabs/on-demand-dynamic-delivery#3)
Near the top of the page there is a link that should open the reference page for SplitCompatApplication, but it returns 404 when pressed.

I think the correct link should be:
https://developer.android.com/reference/com/google/android/play/core/splitcompat/SplitCompatApplication

Open section 4, “Add support for Split Install API in your app,” and locate the SplitCompatApplication reference link near the top. Compare it with the proposed developer.android.com reference URL and update the broken destination. Done means the codelab link points to the SplitCompatApplication reference page instead of returning 404.
