Gitlab now sends X-Gitlab-Event: System Hook for all events

[dren-dk]

It seems gitlab 12.7.5 sends the header X-Gitlab-Event: System Hook for push events in stead of "Push Hook".

I have set X-Gitlab-Event:Push Hook in the ingress in front of Argo CD, which uses dex, which uses webhooks v5 (of some version) and that made the push hooks work just fine, so that makes me think that gitlab simply changed the header value.

Is the reliance on the header wrong or is gitlab broken?
