Doc new pwshw.exe for PS7

[SteveL-MSFT]

Documentation Issue

Waiting on PR PowerShell/PowerShell#10962

Context of the issue

For PS7 we add a pwshw.exe along with pwsh.exe for Windows. pwshw.exe is built as a WinExe which means it won't pop up a console window (which also means you can't use it interactively). It's for admins to run PS7 scripts without popping up a console window on user's desktop. pwshw.exe takes the same command line arguments as pwsh.exe.

Is this ever happening ?

Running a script without popping up a console window is a necessary feature for PowerShell.
Param -WindowStyle Hidden just doesn't cut it.
