Add Vagrant test configuration and installer-equivalent bootstrap

[nicerloop]

Description

• Add Vagrant configuration to run tests in an isolated and clean Windows 10 VM.
• Add just file to run tests in the vagrant box
• Add scoop-bootstrap command equivalent to scoop installer: shim scoop and seed main bucket
• Fix scoop and tests edge cases identified when running in the clean isolated VM

Motivation and Context

I want to fix/extend scoop and need a simple way to test on my personal machine.

How Has This Been Tested?

The objective is explicitly to run scoop automated tests.
So `just tests the way.

@nicerloop Please review #5349 and let us know your thoughts regarding using the built-in Windows Sandbox, vs installing Vagrant. I like Vagrant, but it be more tool than we need.

Vagrant allows me to do scoop development on a macOS host where obviously Windows Sandbox is not available. It also allows me to run linux and macOS virtual machines where I experiment with scoop to install and run windows software through powershell and wine.
