Github Organization Webhook for Package V2 API

[Gerrit91]

Hello. :3

Lately, there exists a Github organization webhook called "Package v2s". It can come in handy because it allows triggering events when container images are pushed to the Github Container Registry.

I assume that the webhook is pretty new because it lacks documentation, but I think it would be more elegant to add it to this project before I start to build something custom on my own.

Would a PR adding this webhook generally be welcome? If yes, I am willing to contribute this addition.

Thanks and regards!
