Expand testing for expanded-view notifications (#2956)

1. Updated the `@metamask/notification-example-snap` to have a method to
trigger an expanded view notification.
2. Updated `test-snaps` to trigger the new methods added above.
3. Updated `snaps-jest` to allow for unit testing of expanded view
notifications.
