The PDK Docker image does not contain any build tools, which causes
the installation of gems that use native extensions to fail.

This commit changes the Docker image used in the Auto Release
GitHub Action from the PDK image to the Puppet dev-tools image,
which contains packages like `make` necessary for building native
extensions.

Modeling after the learnings of the support team in commit
puppetlabs/puppetlabs-puppet_metrics_collector@78dd858

This commit pins the github_changelog_generator gem to its latest
version to make it work, and the concurrent-ruby to an older version
to compensate for the version of PDK shipped in the dev-tools
container image.
