New command to run Domino Server Setup from Windows for IBM i

On IBM i, Flexera InstallAnywhere 2018 is the platform used for the Domino Server Setup wizard on a Windows computer. As a result, the command to run setup from a Windows computer on IBM i is now domwzd.bat. Previously it was domwzd.exe. In other respects, installation and setup on IBM i remain the same as in Domino 11.0.
