Update Toast.tsx to support padding for modal

[manhtruongwang]

Use Toast within modal will cause padding issue, the update will add a padding so Modal can have padding without the header safe area.
Usage:

Toast.show({
        type: ALERT_TYPE.WARNING,
        textBody: t("t_check_your_input"),
        paddingTop: 10, // Default to original padding if not set 
      });
      return;

In Modal wrap the content in
<AlertNotificationRoot>{children}</AlertNotificationRoot>
