Integration with Content Moderation Notifications

Problem/Motivation

I think this module is great and solves a problem that many clients want solved, but it falls short as there's no easy way to tie this functionality in with the content moderation notifications →

Proposed resolution

Add a supplementary module that adds for the ability to enable sending content moderation notifications to the reviewer.

Remaining tasks

TBD

User interface changes

None for this module, but does affect the UI of the content moderation notification settings.
