Microsoft Store version Python supported

[tcztzy]

Microsoft Store version Python provides python.exe, idle.exe and pip.exe, but no py.exe launcher. If a user (like me) only installed this package, without the traditional one, will got error because the hard code way to find Python interpreter.

let output = Command::new("py")

I prefer it to be a feature request instead of bug report, hope you will help people like me.
