Changes at "Improve email received on moderated content"

Is your feature request related to a problem? Please describe.
As a moderator (process-admin), I would like to receive an e-mail with a link directly to the backend for the individual proposal when a message arrives, instead of a link to the frontend as is currently the case.

Describe the solution you'd like
Improve the email received on moderation to incorporate the administration link (if the resource being moderated has one)

Describe alternatives you've considered

Welcome!
