Set the time period for update notifications

Allows you to set the time period, in milliseconds, over which users are notified that Brave must be relaunched or that a Google Chrome OS device must be restarted to apply a pending update. Over this time period, the user will be repeatedly informed of the need for an update. For Google Chrome OS devices, a restart notification appears in the system tray according to the RelaunchHeadsUpPeriod policy. For Brave browsers, the app menu changes to indicate that a relaunch is needed once one third of the notification period passes. This notification changes color once two thirds of the notification period passes, and again once the full notification period has passed. The additional notifications enabled by the RelaunchNotification policy follow this same schedule. If not set, the default period of 604800000 milliseconds (one week) is used.
