feat(gateway): Reduce nvidia-container-toolkit installation

For newer NVIDIA Container Toolkit versions, the components installed
through the nvidia-container-toolkit, libnvidia-container-tools, and
libnvidia-container1 packages are considered legacy. In CDI mode -- or
when native CDI is used -- only the nvidia-container-toolkit-base
package is required with the notable components being:

* nvidia-ctk - The general purpose NVIDIA Container Toolkit CLI. It
  includes functionality such as nvidia-ctk cdi generate to generate
  CDI specifications and nvidia-ctk cdi list to show available CDI
  devices.
* nvidia-cdi-hook - Implements specific container lifecycle hooks used
  to ensure that a container is set up correctly to allow GPU access
  after device nodes and driver files are injected using CDI.
  This CLI is aliased by the `nvidia-ctk hook` subcommand.
* nvidia-container-runtime - As a wrapper for runc to add GPU support
  in environments where direct CDI device requests are not possible.
  This includes k3s, where the nvidia RuntimeClass is added automatically
  if thie nvidia-container-runtime is detected and used to ensure the
  injection of device nodes and libraries for the k8s-device-plugin
  containers.

This change also renames the Docker build stage to nvidia-container-toolkit
explicitly for clarity.
