FEATURE: Staff can receive pending user reminders more frequently. (#13422)

* FEATURE: Staff can receive pending user reminders more frequently.

We now express the "pending_users_reminder_delay"  in minutes instead of hours so staff can have finer control over the delay.

We need to keep in mind that the reminders could still take up to 20 minutes, even when using a lower value. We send them from a scheduled job.

* Migrate to a new site setting for the reminders delay
