Nvidia's DGX Spark: Mini AI Supercomputer Overview and Review

Update: The very first Playbook I tried (unsloth) didn’t work . There was a bad URL and some package version and dependency issues. I figured out how to get it working and completed the playbook, then submitted a PR that fixes the playbook instructions for others. The PR has not been merge as I write this, so if you run into a problem with the Unsloth playbook, see: PR #14: https://github.com/NVIDIA/dgx-spark-playbooks/pull/14
