Add stage/task for annotating pathway pages with links to papers

[khanspers]

Example: https://new.wikipathways.org/pathways/WP1539.html#gsc.tab=0 (see the Cited In section)

Tasks:

• Go through PMC listing to see if it looks like any particular pathways are highlighted, for example:

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9530846/figure/fig5/
Mentions: WP1269 and WP447

• Then go to those pages on the new site and click on the edit icon for Cited In to add the new entry. Click 'Commit Changes’ and the site will rebuild.

But after discussions we decided that this task should be handled in an automated way instead.

The concept of adding articles a pathway was cited in has been added to How to Cite since its still relevant for individual pathway authors.
