Next.js requests to data fetchers are not traced

[lforst]

We don't trace outgoing requests to data-fetchers when navigating: We monkeypatch Route.changeState by starting a transaction when it's called. This doesn't work because the requests to the data fetching endpoints (e.g. getServerSideProps) happen before Route.changeState is called. There are no active transaction when these requests happen so there are no traced requests.

Will this be closed by #5676?

Yes! To actually have traced data-fetchers experiments.autoWrapDataFetchers must be set in the sentry next config but this is practically resolved. Thanks for the reminder!
