Fix windows nightly build failure

PR #29865 changed the target directory for windows to be different from the source folder. However, the 'upload-nightly' command assumes the packages are stored in the default cargo target directory (./target), so the nightly jobs for windows were failing to find the packages.

This PR fixes the 'upload-nightly' command to account for non-default target directories specified via CARGO_TARGET_DIR.

- [x] `./mach build -d` does not report any errors
- [x] `./mach test-tidy` does not report any errors
- [x] These changes do not require tests because they fix a bug in packaging logic.
