The runner name format has changed from an array to a string. Other GPU-related workflows in this repository use array format for self-hosted runners (e.g., [nvidia-docker-b200-8-x86-64] in nvidia_workflow.yml and nvidia-arc-health.yml). While both formats are valid in GitHub Actions, using an array is the conventional format for self-hosted runners as it allows specifying multiple labels. Consider using [gpu-t4] instead of gpu-t4 for consistency with other workflows in the repository.
