Description
I'm working on some integrations which would benefit from associating webhook notifications with alerts returned from the results from alerts/groups. It'd be super useful if this endpoint included the group key for each group.
It looks like the old v1 api did include the group key in AlertGroup (#576) but when the new v2 api was added this field was omitted: #1791
There doesn't seem to be any discussion of the group key in #1791 so my guess is that it was just an accidental removal. Are there any concerns about re-adding this?
