Fail fast on WSL1 while allowing on WSL2

This prevents users from accidentally installing on WSL1 with instructions
guiding how to upgrade their WSL instance to version 2.  Once running WSL2
if you have an NVIDIA card, you can follow their instructions to set up
GPU passthrough and run models on the GPU.  This is not possible on WSL1.
