Fix: compatibility with WSL and Powershell Unix for draw.io diagram

[quintindk]

While testing this script for a customer I was disappointed to see that it didn't generate the Draw.io diagram file when running in Powershell on Windows Subsystem for Linux. Seems to have been a small change i.e. folder slashes and a simple if change.

Tested this on Ubuntu for Windows 22.04 LTS.

just add this validation to the line 762:
if($($args[0]) -like '**')
{
$ModuSeq0 = New-Object System.IO.StreamReader($($args[0]) + '\Extras\DrawIODiagram.ps1')
}
else
{
$ModuSeq0 = New-Object System.IO.StreamReader($($args[0]) + '/Extras/DrawIODiagram.ps1')
}
