Clarify issues links in CONTRIBUTING.md

[JCSzamosi]

This pull request is being submitted to all repos that have been converted to Workbench, so that they reflect a recent update in the Workbench template. The change is probably appropriate for your repository, but you may disagree. I encourage you to look at a description of the problem it fixes found in this comment of this issue.

You will still need to replace example.com/FIXME in the [repo] and [repo-issues] link targets with this repository.

It additionally fixes the broken [how-contribute] link.
