Will do this in a separate PR as this spans multiple packages

This ain't pretty, I know... turns out finding a proper authority regex that isn't ReDos vulnerable is very hard. I think we can leave this as is for now and maybe revisit whenever we sanitize URLs everywhere on the browser side.
(I'd argue that this function should nevertheless be a good base we can reuse later on).

This PR adds partial instrumentation to the client-side
fetchpassed to the universalloadfunctions. It enables distributed traces of fetch calls happening inside aloadfunction.Limitation:
fetchrequests made by SvelteKit (e.g. to call server-only load functions) are not touched by this instrumentation because we cannot access the Kit-internal fetch function at this time. Opened an issue on the SvelteKit repo to find a solution for this.Anyway, here's a fancy screenshot of a successful trace:
My guess is that sveltejs/kit#9542 and sveltejs/kit#9530 are gonna take a little while longer to be resolved. I'd say, we add this in for the moment so that we at least get these traces connected. We should take it out/adjust whenever we have
