How to set up and validate locally

Numbered steps to set up and validate the change are strongly suggested.

1. Enable the FF global_ci_catalog
2. Create a few projects that you will be able to convert to Ci resources. Create them under the admin namespace for ease of testing.
3. Once you have done so, get the ID of the first new project you wanted to convert. Then in the Rails console, run:

projects = Project.where("id > ?", your_first_project_id -1)
projects.each do |project|
  project.update!(description: 'description')  
  ::Ci::Catalog::Resource.new(project_id: project.id).save   
end  

1. Make a release (https://docs.gitlab.com/ee/ci/components/#release-a-component) OR Make a release via Release UI
2. Navigate to Explore -> CI/CD Catalog
3. Check the tooltip in the star count and the released time.
