Update to PDK template 3.0.1

This commit updates this module from PDK template 2.7.1 to 3.0.1.

In addition to the boilerplate changes, this commit also:

- Updates the "auto release" GitHub Action to "release prep," reflecting
  upstream change (puppetlabs/pdk-templates@c3f57b7).
- Removes the github_changelog_generator and concurrent-ruby gems, which
  were previously needed for the release process but are no longer
  necessary in newer release processes in the PDK template.
