## What this change does:
Adds a power-shell script to get the latest release from GitHub and download it if the user does not have it on their disk.
## How to get this working:
Create the following directory structure:
```
---- ventoy
---- ventoy-update-windows.ps1
---- ventoy-1.0.19-windows.zip
---- ventoy-1.0.18-windows.zip
```
When running the script from that directory, it will check the latest downloaded release on disk and compare it with the latest release on GitHub. If a newer version exists, it will download that version in the same directory.
## Future scope of this change:
- Could be added to automate updates within app.
- This approach also allows to get the change-log using `$release.body`.
