Issue:
Support for registry_package events
According to the [documentation](https://docs.github.com/en/webhooks/webhook-events-and-payloads#registry_package) (and [this](https://docs.github.com/en/webhooks/webhook-events-and-payloads#package)) a Github App wishing to receive events for a new/updated package should expect to receive the package event which is the renamed registry_package event. However, what actually happens is that in the permissions section for a Github App there is only the Registry Packages event available and the webhook request title has the value `registry_package`.

Can we please add support for this?

Pull request description:
Add support for registry_package event
as of the time of this writing, the Github documentation describes two events related to packages. One called package and one called registry_package. According to the documentation, users should switch to using the package event instead of the registry_package event. However, when working with the actual permissions and events, there is no package event but there is a RegistryPackage event that can be enabled for a Github App. It looks like the documentation is wrong and the registry_package event was added after the package event and it's the registry_package event that users should expect to receive.

Fixes: #3544.
