[Issue-578] - adjust AuthOptionsResponse parser decode

[anettodev]

When the user has a 2FA with security keys (yubikey), the AuthOptionsResponse cannot be parsed because securityCode attribute is not optional and the AuthenticationError.accountUsesUnknownAuthenticationKind is never shown.

The correct authType for security keys is not implemented and needs to check more the documentation for this.

PS: also, I have updated some missing pt-br localization strings @MattKiazyk

If someone can provide a better doc about idmsa.apple.com/appleauth/auth, "X-Apple-ID-Session-Id", "scnt", "X-Apple-Widget-Key", I can dig a little more.

Already checked the https://developer.apple.com/documentation/sign_in_with_apple/sign_in_with_apple_rest_api

@anettodev support for authentication keys have been added in https://github.com/XcodesOrg/XcodesApp/pull/617 so I'm going to close this PR.
