**Steps to reproduce**
1. Use Page Curation to nominate a new page for deletion (AfD).
1. Repeat step #1.
Page Curation adds the AfD text to the same page, even though it already exists.
Page Curation should create a new AfD page, appending //(2nd nomination)// or //(3rd nomination)//, etc., based on what AfD pages already exist.
See [[https://en.wikipedia.org/wiki/Wikipedia:Articles_for_deletion/Queen_Street_Bus_Terminal|Wikipedia:Articles for deletion/Queen Street Bus Terminal]] for example. The page [[https://en.wikipedia.org/wiki/Queen_Street_Bus_Terminal|Queen Street Bus Terminal]] was nominated by Atsme. If the first deletion discussion page already exists, page curation should add text to the appropriate discussion page instead (i.e. with "2nd nomination", "3rd nomination", etc. in parentheses suffixed to the end of the title) for consistency with Twinkle.
