fix: remove redundant typo code. redundant return statement (S1023)

[tjcchen]

Hi Team,

I ran into this warning info from your Go sample code when I tried to integrate Stripe Payment Service into our product. I think this should be a typo.

func writeJSONError(w http.ResponseWriter, v interface{}, code int) {
	w.WriteHeader(code)
	writeJSON(w, v)
        // redundant return statement (S1023) go-staticcheck
	return
}

But anyway, your sample code & videos are really helpful to us. Thanks much for your dedication and effort!

Regards,
Andy
