Update variable `root_cause` query of Deployment Blockers dashboard
As discussed in this MR thread, we need to update the query for the template variable $root_cause
so that we can filter only those with blockers count greater than 0 for the selected time range.
Check this test dashboard link .
You can also generate the JSON file using this script: ./dashboards/generate-dashboards.sh
and then import it in the Grafana Playground folder
