Upgrade JupyterHub to 4.3.2 and JupyterLab to 4.5.3 (#51)

* Fix gpu_type to be conditional on NVIDIA flag in kind.sh

The gpu_type Terraform variable was unconditionally set to "nvidia",
causing the CUDA JupyterHub image to be referenced even on macOS
where NVIDIA GPUs are not available. Now gpu_type is set to "nvidia"
only when --with-nvidia is used, and "none" otherwise.
