Adapt new project boostrapping to GH Actions #978
Description
See above.
We have https://github.com/Gizra/drupal-starter/blob/main/robo-components/BootstrapTrait.php
Make sure we can create new projects based on Drupal Starter, with GH Actions easily. Look around what needs to be adapted / streamlined.
Check README.md on how it's supposed to work, adapt, if needed.
