Demo content to be installed as an option rather than by default

I tested it using these steps:

git clone git@git.drupal.org:issue/droopler-3500842.git droopler1
cd droopler1
./launch-droopler-cms.sh
ddev launch

In the browser, I get a standard installation process without any option to check or uncheck demo content installation.
Are my testing steps correct?

Works fine after changing branch:

git clone git@git.drupal.org:issue/droopler-3500842.git droopler1
cd droopler1
git checkout origin/3500842-default-content-option
./launch-droopler-cms.sh
ddev launch

You can merge it to the main branch and release a new version with this option.
