Turning off validation notification within TM

[Jorieke]

Describe the bug
The notification for a validated task cannot be turned off. It would be great if you could turn that off, not just as an email, but as well as a notification in the TM.

To Reproduce
I switch off in my settings Tasks validation emails - Receive an email when a task you have contributed to is validated:

But I still get notifications in the HOT TM about validated tasks:

I think it is the same for the Team Announcement emails, and maybe the others as well. I can however not show you an example for that.

Expected behavior
It would be great if you would turn of the notification to have it both for the email notification as the in TM notifications.

Additional context
Thank you for all your hard work team!
