WSL Ubuntu additional notes

[JohnCRuf]

Two new notes need to be added to the WSL ubuntu entry.

1. It is not proper to install vscode within the WSL ubuntu environment. The installation should be done in windows and then transferred to ubuntu via the procedure outlined in this link: https://code.visualstudio.com/docs/setup/windows
2. If export DISPLAY:=0.0 does not work, then you should use the commands:
   export DISPLAY=$(awk '/nameserver / {print $2; exit}' /etc/resolv.conf 2>/dev/null):0 export LIBGL_ALWAYS_INDIRECT=1

This automatically selects the correct display port. It doesn't continuously fix the issue but its good enough as a stop-gap.
