Bare control-repo doesn't pass "pdk validate" tests

[bschonec]

Describe the Bug

The site-modules/adhoc/plans/myplan.pp file doesn't pass a basic 'pdk validate' run.

Expected Behavior

It's expected that control-repo should be able to pass any PDK tests from the main/master branch.

Steps to Reproduce

Steps to reproduce the behavior:

1. git clone https://github.com/puppetlabs/control-repo.git
2. cd control-repo
3. pdk convert (accept all defaults)
4. pdk validate

Environment

Red Hat Enterprise Linux 7.9
pdk-2.6.1.0-1.el7.x86_64
puppet-agent-7.16.0-1.el7.x86_64
