Improve Japanese translation of "Notification on" and "Notification off" in customer view

Problem Definition

Currently in the customer view, the Notification on is displayed as "通知を受け取る" which translates to "Receive notification" and Notification off is displayed as "通知をオフにする" which translates to "Turn off notifications"

Suggested Solution

Improve the translation to show Notification off as "通知をオンにする" which translates to "Turn on notifications" since the notification is already off.
