Change Notification models are missing

[nshttpd]

The Java SDK has models for ChangeNotification and ChangeNotificationCollection to Unmarshal into when handling webhook notifications from Subscriptions, but these and other associated models seem to be missing from the Go SDK.

Is this possibly because of how the Go SDK is autogenerated that these are missing because they are not part of an API Request, but on the receiving end of data?

Hi @nshttpd
Thanks for reaching out and for trying the Go SDK.

You're absolutely right, these models are missing because they are not referenced by any API in the API description. And by design kiota, our next generation SDK generator, only generates the models as they are needed.

The easiest way to get those models would probably be to:

1. Take the existing OpenAPI description
2. Add a placeholder path item that returns change notifications
3. Clear any other endpoint
4. Use Kiota to generate the models
5. Place the models in this core library under a models package (so they can also be used in beta)

Do you think this is something you'd be willing to submit a pull request for?
