VirtualBox 7 Compatability Changes

- Created a PowerShell script `virtualbox-wrapper.ps1` to wrap calls to vboxmanage and only exit once the virtual machine has been terminated.
- Updated launch.json to use the PowerShell launch type to launch `virtualbox-wrapper.ps1` with the machine name supplied as an argument.
- Updated `readme.md` to reflect these changes.
