Subject: [PATCH] fix: apply default export interop to `next/config` (#40224)

The `next/config` code generated is incompatible with the `type: "module"` setting in `package.json`. This PR makes sure that we append the same interop code to the output `shared/lib/runtime-config` file as other re-exported modules:
