Documentation for adding scopes missing from the main docs?

[crspybits]

I wasn't seeing anything about adding scopes at the main doc page: https://developers.google.com/identity/sign-in/ios/quick-migration-guide.

Also, in the main docs, the section:

"Retrieving user information
Once the user has authenticated and authorized access to the scopes you request, you can access user profile information through the GIDGoogleUser object."

(https://developers.google.com/identity/sign-in/ios/people) it makes it sound like you can explicitly request scopes prior to the addScopes call.

We do have incremental auth docs under Client-side Access, but I think we could do a better job calling attention to them.

I think you're right to point out that the Get(ting) Profile Information docs still have some content that was held over from v5 and need an update.
