fix(ci): skip GPU integration tests when no GPU available

The packaging Verify Package step runs runtests.sh --net which requires
GPU for deepedit/segmentation integration tests. On ubuntu-latest runners
without GPUs, these tests would always fail. Add an nvidia-smi check to
skip gracefully and explain why.
