This PR #21350 added the new `PrivacyInfo.xcprivacy` to our default templates (new requirement from Apple) when building from Windows we try to bundle this resource and unfortunately we are missing the required Link metadata when this is done from single project triggering a condition where the path is incorrectly calculated when zipped in windows and once the zip archive is transfered to the mac host it is unable to unarchive the file. To fix this we simply unify the logic with what the macios SDK currently does [1] this ensures the right bundling happens.
