Iss #161 - Add merge_group webhook support to the webhook callback

• Iss #161 (closed) - Add merge_group webhook support to the webhook callback

A commit status is required for merge queues as separate branches w/ different SHAs are created, which no longer contain the ECA check status. As all commits in the queue will have been validated, we can just send a request to create the missing commit status without checks.
