[ProjectHelper] feat: Add integration with Notificationshelper

[rulasg]

Integrate NotificationsHelper with ProjectHelper:

• Index notifications by URL
• If notification is loaded we can Get-NotificationForUrl to get the notifications information; Yet to decide were or when. Just in Show command or also on Get; Maybe add a WithNotifications switch to Get-ProjectItemsList
• Add Update-Notifications to the Update-Project or similar process
