This will allow for alternative images to be built from (i.e. puppet/pdk:nightly)

Unsure if there is a workaround (or me doing something wrong), or if make should be installed via the dockerfile or in the pdk source image.

In the meantime I have fallen back to using the following in my repo actions:

name: Run unit tests

    on:
      - push
      - pull_request
    
    jobs:
      validating:
        runs-on: ubuntu-latest
    
        steps:
        - name: Clone repository
          uses: actions/checkout@v2
        
        - name: Setup ruby
          uses: actions/setup-ruby@v1
          with:
            ruby-version: 2.5.9
    
        - name: Install bundler and gems
          run: |
            gem install bundler
            bundle install --jobs 4 --retry 3
    
        - name: Run unit tests
          run: |
            bundle exec rake rubocop
            bundle exec rake release_checks

Hi Team,

This is just what I was looking for!
I noticed, that specifying puppet version works on the validate action, and this one seems to contain everything on main branch, but it is not released. Tag v1 (and v1.0.0) do not contain the latest changes.

May I ask that you release a version with the latest changes in main (so I can pin my action to that version)?
