    GitHub Action for PSDevOps
.Description
    GitHub Action for PSDevOps. This will:

    * Import PSDevOps and Connect-GitHub (giving easy access to every GitHub API)
    * Run all *.PSDevOps.ps1 files beneath the workflow directory
    * Run a .PSDevOpsScript parameter.


    If you will be making changes using the GitHubAPI, you should provide a -GitHubToken
    If none is provided, and ENV:GITHUB_TOKEN is set, this will be used instead.
    Any files changed can be outputted by the script, and those changes can be checked back into the repo.
    Make sure to use the "persistCredentials" option with checkout.
