Feature Requests Top-level JSON object in webhook payload

Currently, the webhook payload is a JSON array at the top level, for reasonable reasons. Unfortunately, for example Grafana OnCall doesn't support that and will fail to parse any webhook that isn't an object at the top level. This is trivial to translate in some sort of middleware service, of course, but then that needs to run somewhere and runs into issues with what infrastructure it should be on in order to work when the shit hits the fan, etc.

So it would be nice to be able to say that the top level payload should be an object. It is still fine if there are multiple events in it, just that instead of [ev1, ev2] we could have something like {"events": [ev1, ev2]} and it could be parsed.
