Cannot run Schema.org Blueprints Demo

not sure but I believe it may be necessary to add:

composer config minimun-stability dev

It doesn't seem like composer config minimun-stability dev would fix it. The requested version was

1.0.0-alpha5 
 

but Composer says the only versions are dev-1.0.x, 1.0.x-dev

I think I found the problem:

composer require 'drupal/schemadotorg_demo-schemadotorg_demo:^1.0@alpha'

Notice how the package name for composer is schemadotorg_demo-schemadotorg_demo? Something else is holding onto schemadotorg_demo. I bet the latter does not have an alpha release.

I looked at the API and there is nothing about the Composer package name: https://www.drupal.org/api-d7/node/3319147.json →

The release does not contain the Composer package name either: https://www.drupal.org/api-d7/node/3448370.json →
