fix(ios)!: use NEHotspotNetwork vs deprecated CNCopyCurrentNetworkInfo for wifi info, iOS14+ required (#791)

BREAKING CHANGE: iOS 14+ is new minimum, that's react-native 0.76+

The first react-native version to require iOS 14+ was react-native 0.76 so that is
pretty old but this still may be a breaking change for some people so we are noting it.
