feat(users/Profpatsch/whatcd-resolver): log json+ld fetching r/7709

This traces the target of a json+ld fetch.

We also simplify the telemetry stuff by using a pseudo-class
`MonadOtel` everywhere.

I wonder if we can get rid of passing the span to `assertM`, because
it’s kind of an antipattern to be honest.
