Add OCI standard image labels

[karthikvetrivel]

This PR adds well-known OCI Image labels to the gpu-driver-container image metadata.

Before

$ docker inspect --format='{{json .Config.Labels}}' nvcr.io/nvidia/driver:580.95.05-ubuntu24.04 | jq
{
  "org.opencontainers.image.ref.name": "ubuntu",
  "org.opencontainers.image.version": "24.04"
}

After
(pending CI build)

[rajathagasthya]

suggestion: add an org.opencontainers.image.description="Provision the NVIDIA driver through containers".

Optionally, remove the plain description label above or match its value as well.
