[expo-google-sign-in][ios] Upgrade GoogleSignIn pod to 4.4.0 (expo#2933)

# Why

Fixes expo#2932, also an ordinary dependency upgrade.

# How

- set the version of `GoogleSignIn` in `EXGoogleSignIn.podspec` to `~> 4.1` so that developers installing `EXGoogleSignIn` pod in projects without `ExpoKit` don't have to install `GoogleSignIn` separately. We could also add instructions to add `GoogleSignIn` pod dependency to setup instructions of the pod.
- run `pod update GoogleSignIn` in `ios`

# Test Plan

Project compiles and Google screens in NCL work 👌
