fix: adjust dead documentation link
Summary
Fix a dead documentation link, the puppetlabs.github.io pages seem to be gone.
It seems the link is still broken, will the content be available at some time? If yes, this PR could be closed.
Hi @ekohl, @bastelfreak, @smortex, the link is still broken. If it will be fixed sometime we can close this PR, otherwise think about approving it.
Any News on this topic?
@ThomasMinor you're pinging the non-Perforce people but IMHO they are responsible for the CONTRIBUTING.md file. Given their recent blog post I'm not sure if they actually want people to contribute at all so I'm not going to be helpful here.
Since this doesn't get anywhere, I close the PR.
