feat(node): Add new options to nativeNodeFetchIntegration (#15282)

<!-- Use this checklist to make sure your PR is ready for merge. You may
delete any sections you don't need. -->

## DESCRIBE YOUR PR

This is the documentation for
getsentry/sentry-javascript#17996 (it also adds
the missing `spans`).

Now I think I did a little hack, since these options are not available
in `node-core`, but `javascript.node-core` is not a identifier. So I
show a little warning for only `javascript.node` that it is not
available in the `node-core` package. Since all other integrations use
`@sentry/node` anyways, we don't have to show this warning so that is
why I use the `<PlatformSection />` as well.
