CKEditorModule does not have a module def (ɵmod property) in Jest test

We're upgrading from Angular v12 to v14 and most of the tests fail as the CKEditorModule, defined in our app.module does not have a emod property

The actual Jest error:

    CKEditorModule does not have a module def (ɵmod property)
