Source spec does require outdated fields for SPEC and STATUS

[matzew]

Describe the bug

For sourceSpec and StatusSpec the "Sources Spec" does require still explicit fields for

• Sink
• CloudEventOverrides
• Status
• SinkURI

See here for reference: https://github.com/knative/eventing/blob/main/docs/spec/sources.md#source-custom-objects

However, looking at the code, the actual types now leverage the SourceSpec type for this. Two examples:

• https://github.com/knative/eventing/blob/main/pkg/apis/sources/v1/apiserver_types.go#L53-L58
• https://github.com/knative/eventing/blob/main/pkg/apis/sources/v1/ping_types.go#L54-L59

and the SourceStatus for the Status:

• https://github.com/knative/eventing/blob/main/pkg/apis/sources/v1/apiserver_types.go#L94
• https://github.com/knative/eventing/blob/main/pkg/apis/sources/v1/ping_types.go#L95
