Update instructions to ensure M1 version is used (#7086)

Right now CocoaPods will treat the `M1` as a beta designation, pulling in `7.X` over `7.X-M1`. The only way at the moment to pull in the proper M1 version is to explicitly specify it. We'll need to look into a way we can do this in a more user friendly way.
