[Feedback] Group or highlight iOS vs Android specific configuration that can be easy to miss.

**Page**: [`/lib/auth/social/q/platform/[platform]`](https://docs.amplify.aws/lib/auth/social/q/platform/react-native)

**Feedback**:
Client specific configuration is a bit scattered and should be grouped or somehow highlighted. Specifically the iOS specific instructions for `Info.plist` and `*AppDelegate.m`

If I need specific guidance when following this doc, it can be easy to miss what client specific configuration is needed, unless I go through the whole page from the top to the bottom. Revising this page to either 1) Group them together or 2) Highlight them on the right navigation can improve the experience for returning users.
