Move podspec to where "react-native link" expects it to be

@mars-lan Thanks for this, but we have deliberately not put the podspec here because we want react-native link to link the .xcodeproj file and not the Pod by default.

By using the .xcodeproj file, the process can be completed without user intervention.

If we use the podspec, then the user would have to ensure that React is also installed as a Pod, something that can be difficult to get working.

We have kept the podspec to allow people to use Cocoapods if they wish to.

Unfortunately react-native link doesn't seem to work well for podspecs outside of project root and keep adding .xcodeproj even after adding pod RNFirebase to Podfile :(

@mars-lan We flagged this with the person that made the change in RN, but unfortunately they have not done anything about it to allow us to configure its usage:
