feat: Add missing notification_setting to Team

[stevehipwell]

This PR adds the missing notification_setting field from the Team type (it was already present in NewTeam).

[stevehipwell]

I've fixed the failing tests, the notification_setting were being returned in a test that wasn't using them until now.

Thank you, @stevehipwell !
LGTM.

Merging after tests pass.
