Issues encountered should indicate whether the github issues have been closed

For example, see the "Issues Encountered" here: https://runfo.azurewebsites.net/view/definition/1080/.
dotnet/runtime#64280 has been closed but there is no indication of this in the runfo UI.

Agree. Need to begin listening to events for issues, tracking them and updating them in the UI.
