[BE] Wiki Activity should be supported on Project, Group and User Activity Pages
This is a placeholder issue for Backend related work for #14902 (closed)
Such work includes:
- designing models for the event data. It is evident that we need to store metadata about wiki pages, and keep this up to date with their current title and slugs in order to link to them correctly
- adding hooks in the services to keep this data up-to-date on CUD
- adding views to the activity feed to display wiki events
