Invalid link in project forking docs
In this page in the document about Project forking workflow, https://docs.gitlab.com/ee/user/project/repository/forking_workflow.html there are a link to a blog page that isn't valid any more. https://about.gitlab.com/blog/2016/12/01/how-to-keep-your-fork-up-to-date-with-its-origin/
That process that is described there doesn't work. And the UI has changed since then.
A second issue is that the document about mirrowing a repository doesn't work.
