Updates to the /working_groups resource

This is the data that we need to capture and serve via /working_groups

The challenge here is getting this content. Paul mentioned that @zahrafazli can help us with this.

@zahrafazli can you provide a list of all participation levels for each WG.

I think we can manage to get everything else once we have this list of participation level per WG.
