The deploy script assumed the PVC was mounted on the CI runner at /mnt/headlamp-plugins, but the runner pod doesn't have that mount. Fix by using a temporary pod (kubectl run) that mounts the PVC, receives the plugin tarball via stdin, and extracts it. Also adds missing workflow steps to create the PVC and upgrade Headlamp with the shared volume helm values before deploying. Co-Authored-By: Paperclip <noreply@paperclip.ing>
