Ignore SSL certs on PowerShell core

[VincentBerger]

The method you used to ignore SSL certs does not work on non-Windows platforms with PowerShell core, MacOS in my case, due to missing .Net dependencies. This is the error I'm getting on Mac:

add-type : (3,40): error CS0246: The type or namespace name 'ICertificatePolicy' could not be found (are you missing a using directive or an assembly reference?)
    public class TrustAllCertsPolicy : ICertificatePolicy {
                                       ^

If I remove all the code in Set-InsecureSSL, and use the -SkipCertificateCheck switch on the Invoke-RestMethod call in Invoke-OVGDRequest, then it works

That switch was introduced in Powershell 6. I need to support 5 (and desktop) so need to find a way to get around it

I was playing with this today and found that PowerShell Core 7.5.1 on Windows 11 doesn't work either.
I am totally not that good, but I hacked my way past all the errors and got it to work.

1. Private\Set-InsecureSSL.ps1
   I butchered this file and just use a single command for Core to ignore SSL

function Set-InsecureSSL {
    [cmdletbinding(SupportsShouldProcess)]
    param()

    if($PSCmdlet.ShouldProcess("ShouldProcess?")){
	[System.Net.ServicePointManager]::ServerCertificateValidationCallback = { $true }
    }
    # else {
    # }

}

2. Add a Core friendly switch to Private\Invoke-OVGDRequest.ps1
   I added to the very end of line 46: -SkipCertificateCheck

Maybe one of you smart people can make it so the module detects what version of PowerShell it's being run under, and if above a minimum version, incorporates these/similar changes?
