AppOpenAd.Loadが、CS0618の警告を出す件の修正方法

警告詳細

warning CS0618: 'AppOpenAd.Load(string, ScreenOrientation, AdRequest, Action<AppOpenAd, LoadAdError>)' is obsolete: 'Use Load(string, AdRequest, Action<AppOpenAd, LoadAdError>) instead.'

Loadを、以下のように修正

AppOpenAd.Load(GetAdUnitId(), request, (appOpenAdd, loadAdError) =>
{
}));
