HTML Boilerplate: Add terminal command for opening browser in WSL

[brianrainer]

Because

Hi, I'm following the Odin Project using WSL, and I foolishly spent a couple minutes trying to open a browser from wsl terminal before I find the correct command is using wslview. I know WSL is still not recommended at this stage but I want to contribute a small change that hopefully will help others like me.

Thanks for the suggestion and for wanting to contribute! WSL support is in the making but until that time we will not mention it to avoid confusion since we don't offer support for it and all lessons will assume that the learner uses our recommended OS.
