Important Note for Reviewers
While trying to test this change, I discovered that the developer environment build is currently failing due to an expired GPG key for the Puppet 6 repository.
This PR does not fix that issue, but I have opened a separate bug report for it here: [#3396]
The CI build for this PR will likely fail because of that unrelated error.
