Migrate legacy Scaffolder template & custom actions to ARC Platform (Node 20) #244
Description
Our SourceFuse Backstage backend (Node 18) shipped three Yeoman-based Scaffolder actions run:microservice, run:extension, run:scaffold plus the microservices-monorepo template ( https://github.com/sourcefuse/arc-api-backstage-templates/blob/main/templates/microservices-monorepo-template.yaml ). The scope is not limited to this template we will migrate all needed templates one this is completed.
The new ARC Platform (https://github.com/sourcefuse/arc-platform ) runs Backstage on Node 20 and cannot execute these actions.
Goal is to Re-implement the three custom actions with the modern Backstage @backstage/plugin-scaffolder-node API, package them as an internal backend plugin, and update the template so it runs successfully on ARC Platform.
