Duplicate Post FR: show link to the R&R copy in the notice

[BobBreukhoven]

https://yoast.atlassian.net/browse/DUPP-31

We have a feature that shows a notice in the editor screen when you edit a post that already has a draft to republish:

A duplicate of this post was made. Please note that any changes you make to this post will be replaced when the duplicated version is republished.

It would be great if we would improve this with a link to that draft from that editing screen.
