fix: set wsl.useWindowsDriver when the nvidia-ctk is enabled

This improves the user experience as whenever the user enables the
`config.hardware.nvidia-container-toolkit.enable` option, they cannot
use their Nvidia GPU's within the Docker containers because of missing
libraries.

This gets fixed by setting `wsl.useWindowsDriver` explicitly when the
user requests to enable GPU support on Docker containers.
