Ensure all required Content Types are available before Get-PnPSiteTemplate

Summary

If one of the Content Types you are using on your master site is part of a Content Type Hierachy, you need to ensure that all the Content Types are available on the site before you use the Get-PnPSiteTemplate cmdlet. This will ensure that you can deploy the Template without any issues.
