Notification NOTIFICATION_TYPE_FORMAT_NEEDS_APPROVED_SUBMISSION is not updated&displayed

[jardakotesovec]

Describe the bug
While working on reviewing what notifications we display in current workflow, I run into one OMP notification, which works in 3.3, but not in 3.4/3.5.

To Reproduce
Steps to reproduce the behavior:

1. Go to Submission which is in Production stage but not yet published
2. See notification in 3.3 but not in 3.4/3.5

Investigation
I think that this notification is created in PKPApproveSubmissionNotificationManager.inc.php, when this notification update is triggered - https://github.com/pkp/pkp-lib/blob/stable-3_3_0/classes/submission/form/PKPSubmissionSubmitStep4Form.inc.php#L161

I suspect this was not carried over to 3.4.0.

What application are you using?
OMP 3.4/3.5
