        For device flow / device code login:
        PowerShell requests device and user verification codes and gets the authorization URL where you will enter the user verification code.
        In GitHub you will be asked to enter a user verification code at https://github.com/login/device.
        PowerShell will keep polling GitHub for the user authentication status. Once you have authorized the device,
        the app will be able to make API calls with a new access token.

        .EXAMPLE
        Connect-GitHubAccount

        Connects to GitHub using a device flow login.
