How to set up and validate locally

1. Disable feature flag :glql_work_items:

   echo "Feature.disable(:glql_work_items)" | rails c

2. Create an epic GLQL query:

   ```glql
   display: table
   fields: state, title, updated
   query: type = Epic and group = "gitlab-org"
   ```

3. The state column should display properly.
