How to test this?

There are two ways of testing this depending on whether the backend part is ready or not.

If the backend is done

Enable the feature flag:

echo "Feature.enable(:pipelines_security_report_summary)" | spring rails c

If the backend isn't ready yet

Mock some data to be fed to the filters:

diff --git a/ee/app/assets/javascripts/security_dashboard/components/security_dashboard_vuex.vue b/ee/app/assets/javascripts/security_dashboard/components/security_dashboard_vuex.vue
