Remove unused call to RenderService in ProjectsController
Follow up from !60676 (merged)
We didn't want to risk removing it as part of that security fix.
I'm 80% sure that the returned value is not used, so the call is useless:
Events::RenderService.new(current_user).execute(@events, atom_request: request.format.atom?)
https://gitlab.com/gitlab-org/gitlab/-/blob/10491f27a0fefc79fa2b7d6adfdb11c8040d76d5/app/controllers/projects_controller.rb#L382 doesn't actually do anything and can be removed?
