feat(discord): status based notification suppress switches

[Maxme-L]

Summary

In this pull request, the following changes are made:

• Replace the single discordSuppressNotifications switch with suppress switches depending on the status of the notification

The added switches allow one user to suppress notifications, thus, the selected status notifications won't generate any ping on push notifications.

Minor Breaking Change: the previous switch is completely replaced by the two new ones, disabled by default. Users who had toggled the suppress switch will have to do it again.

Resolves #7619
