Document Windows usage

[bobbicodes]

Having successfully set up the first Windows machine I've used since the 90s, I'm happy to report that installing and using Babashka on Windows is a breeze.

I would like to add documentation that will:

• Describe how to install Babashka with the scoop package manager
• How to use Babashka in WSL

The second option will be mostly the same as the instructions for Linux. At this point I think that any serious developer will want to be able to use it under either shell.
