Fix fetching of libcugraph info

[BradReesWork]

This was just a temp fix to all testing. the code should pull libcugraph from the same place as the other packages.
THis is dependent on cuGraph pushing the package

if [[ $PROJECT == "libcugraph" ]]; then
echo "TMP (FIXME) downloading xml for ${PROJECT} into ${XML_DIR}. Environment variable XML_DIR_${PROJECT^^} is set to ${XML_DIR}"
curl -O "https://raw.githubusercontent.com/BradReesWork/data/main/xml.tar.gz"
else
curl "https://d1664dvumjb44w.cloudfront.net/${PROJECT}/xml_tar/${RAPIDS_VERSION_NUMBER}/xml.tar.gz" | tar -xzf - -C "${TMP_DIR}"
fi
done
