Please correct me, but I don't see new retry logic added, only context timeout added.

[zepatrik]

I realized that we already had an update of ory/x in a different PR, so the retry logic there is already on master 👍
However, I do not agree that we want to decouple the request context from the webhook, at least not for blocking hooks. Non-blocking hooks already have their own context, so I think we should keep that as is and just pick the log improvements from this PR.

Looks good :)
