How can we identify WSL (windows subsystem for linux)

### Your question:

I've seen most recently a few error reports with people trying to use GPU packages with Windows Subsystem for Linux.

* Confirmed: https://github.com/conda-forge/pytorch-cpu-feedstock/issues/317
* Likely: https://github.com/conda-forge/tensorflow-feedstock/issues/410

Basically, we are already pretty thin on maintainers that daily drive windows https://github.com/conda-forge/miniforge/issues/599

it would be good if similar to `ubuntu` wsl would appear somewhere in the `conda info`

Though I'm not sure where it comes from.
