Merge branch '20254-create-mr-for-new-branch' into 'master'

last_push_event widget considers fork events on the main project

Push events on the fork of the current project are considered to be shown besides the push events on the current project. Before we just consider fork events if exists a fork so we miss current project events if the current user has a fork.

Closes #20254

See merge request !5978
