Make MSStore Developer CLI installation easier on CI/CD environments.

There is no simple way of installing the Microsoft Store Developer CLI in Azure DevOps or GitHub Actions.
We need to provide either a native GH Action and extension to install it, or at least scripts to help with this.

Solved #10, which is the 1st step for this issue.
I'm building a github action/script to setup msstore which will download the zip/tar.gz bundles, extract, and add to path.

Solved for GitHub Actions. Still need to work on a more generic solution (powershell script maybe?).
