[DominikB2014]

fixes #10206

Adds the following data to resource spans
url.scheme -> scheme of the resource (https, http, etc)
server.address -> the host of the resource (sentry.io, github.com, etc)
url.same_origin -> wether the resource was fetched from the same origin or not. i.e is a relative resource

Let's make sure we update https://github.com/getsentry/sentry-javascript/blob/develop/packages/tracing-internal/test/browser/metrics/index.test.ts with some tests!

[AbhiPrasad]

make sure you rebase to get the latest fixes from develop branch, and then we can merge!

Just for reference for the next time, make sure to use squash and merge :) (we sadly can't enforce this right now because we depend on merge commits for gitflow, so you have to make sure to select the correct merge manually 😬 )

[DominikB2014]

@mydea Yup! That's my bad, i'm so used to squash being the default and only option.
Looks like supporting squash and merge by branch is quite a common request https://github.com/orgs/community/discussions/10809
