Ruby On Rails on Ubuntu on Windows 10

Thanks to WSL2: Windows Subsystem for Linux on Windows version 2, 
whole Linux (select distributions) can run "natively" on Windows,
transparently, without "virtual machines". 

With that, all Linux (unix) tools become directly usable.
Ruby on Rails installer takes full advantage of that, 
much simplifying possible compatibility issues.
