Need iOS 12 support

[ejaz47]

iOS 13 is available on iPhone 6s or later (including iPhone SE). That means both iPhone 5S and iPhone 6 don't make the list and are forever stuck with iOS 12.4.1.

iPhone 5S and iPhone 6 devices still exist in the market and lot of users are using it hence we cannot neglect these devices.

Not to mention the old iPads, i.e. iPad Mini 3

Native Sign in with Apple is an iOS 13 feature, there is no support for it in iOS 12 and bellow.

The only way to add Sign in With Apple on iOS 12 and older and other platforms is to use Sign In With Apple alternative via manual request:
https://developer.apple.com/documentation/sign_in_with_apple/sign_in_with_apple_js/incorporating_sign_in_with_apple_into_other_platforms?language=objc

But i would say that is out of scope of this plugin, and if you need it, you can implement your own solution based on the provided documentation.

"Platforms that support custom URL schemes—iOS 12.0 and earlier and Android—must handle the data resulting from the authorization flow by storing it on their app server in the logic of their redirect_uri endpoint. You must then redirect the custom URL scheme to give control back to the app."

So why not doing it for everybody?
