Update SDDS Tugboat to get default config and content imported

Actually, that image is coming from the themes so maybe that's a permission issue?

Ah, yes, console shows a 404 for:

https://mr101-hfagpamcycjtiie2ccqvu335hh0pbbmq.tugboatqa.com/themes/contrib/demo_design_system/starshot_demo/assets/starshot/testimonial_avatar.png

so must be a permission issue?

Updated approach to use https://github.com/phenaproxima/xb-demo. This creates a new composer project in the drupal root using xb-demo. Then we add a Composer repository to the demo_design_system checkout as a `path`. Then we composer require the `dev-main` version constraint of demo_design_system. For this to work, we need to modify root the composer.json from `drupal/civictheme` to `drupal/demo_design_system`.

Thanks so much!
