Merge branch 'feature/improve_wiki_page_events' into 'master'

Include Wiki attributes in Wiki page events webhook

The hook data we are sending is not 100% correct (we send details of the project, but should also send details of the "ProjectWiki" attributes like URLs and repositories relative to the wiki itself).

This is a follow up to #17506

Fixes #17507

See merge request !4138
