Docs don't specify package name for some types

Please Describe The Problematic Behavior
Copying the stubbed out code from the documentation (which is very helpful, by the way!) produces errors like these:

activitypub/activitypub.go:74:94: undefined: Activity
activitypub/activitypub.go:92:72: undefined: FederatingWrappedCallbacks
activitypub/activitypub.go:98:68: undefined: Activity
activitypub/activitypub.go:116:94: undefined: Activity

Please Describe The Expected Behavior
The examples should be like this

func (*myService) PostInboxRequestBodyHook(c context.Context,
	r *http.Request,
	activity pub.Activity) (context.Context, error) {
	// TODO
	return nil, nil
}

Note pub.Activity instead of Activity
