How to set up and validate locally

1. Create a new group
2. Import https://gitlab.com/lorenzvanherwaarden/security-reports-with-few-dependencies/ project in this new group (make sure the project name is quite long so it will show the truncation later on)
3. 2. Import https://gitlab.com/gitlab-examples/security/security-reports project in this new group
4. Run a pipeline on both projects
5. Go to http://gdk.test:3000/groups/<your-group-name>/-/dependencies
6. Click on any "x projects" in the Project column and validate that the 1st project's name is truncated
