The file CONTRIBUTING.md contains a list of links that points to
different parts of the developer documentation.
Unfortunately, this list is now incomplete and contains a dead link for the
Developer Workflow.
Given that a more complete similar list is present at:
https://forgejo.org/docs/latest/developer/, this patch removes the
duplication of information, which leads to dead links and
maintenance burden, and replaces the list with simply a link to the page
that has all the current links.
