Update error in example in the README.md for cdevents.AsCloudEvent(event)

[bradmccoydev]

In the readme file the example of sending the event as a cloudevent is wrong as it cannot initialize 1 variables with 2 values. It is missing the reference to err.

Current:

ce := cdevents.AsCloudEvent(event)

Should be:

ce, err := cdevents.AsCloudEvent(event)

as per pkg/api/bindings.go line 153

// AsCloudEvent renders a CDEvent as a CloudEvent
func AsCloudEvent(event CDEventReader) (*cloudevents.Event, error) {
	if event == nil {
		return nil, fmt.Errorf("nil CDEvent cannot be rendered as CloudEvent")
	}
	// Validate the event
	err := Validate(event)
	if err != nil {
		return nil, fmt.Errorf("cannot validate CDEvent %v", err)
	}
	ce := cloudevents.NewEvent()
	ce.SetSource(event.GetSource())
	ce.SetSubject(event.GetSubjectId())
	ce.SetType(event.GetType().String())
	err = ce.SetData(cloudevents.ApplicationJSON, event)
	return &ce, err
}
