Emails: resurrect template notification (#18686)

* Emails: resurrect template notification

* Phantomjs (oh yeah, there is another dev dep phantom :-) was failing for
  the generation of the html templates so I had to update the dependencies
  in order to fix it. While doing that I update the scripts field and docs
  for it as well. yarn.lock is included

* Move splitting of the emails to separate helper function, since more services
  coming up that would need to use this functionality

* Add support for enterprise specific email letters. Probably could
  be done in the better way, but it's not a priority right now
