fix: 🐛 only check webhook payload for what we are interested in
checking the payload in details (eg if the URL field is well formed) while not using it afterward is not useful. It even lead to breaking the webhook after https://github.com/huggingface/moon-landing/pull/4477 (internal link) where the "url" field format had changed.
