Remove the PowerShell module from the SCMU installer #3288
Description
Required for #3152
Requires #3287
Once users have been warned that the Powershell scripts distributed with SCMU will no longer be updated, the next step is removing the PowerShell module from the SCMU Installer. At this point, users of the PowerShell module should be aware of the version on the PowerShell Gallery. The users that are not aware of them yet will be the ones that have missed updating multiple versions of ServiceControl, or have not read the warnings displayed when using the module.
An informational message should also be displayed in the SCMU application stating that it will no longer be distributed as an installable application in the future and will instead be a self-contained application.
This is not a breaking change even though we are removing a management mechanism that users may be relying on, as the same module they rely on will already be distributed via the PowerShell Gallery. This can be done in a minor version.
