[WIP] Solve cross-platform import problem on MacOS build

[stuartpreston]

Fixes #909

This change might solve the problem with the MacOS build.

Note: Unfortunately I encountered further errors in the build on my local machine to do with the New-Json function either not correctly establishing the path to the test repo I'm likely missing a dependency since Get-CheckRepo isn't available on my machine so submitting this PR first to see if it gets us any further.

This was my first thought also but unfortunately, we must have postimport.ps1 run for the module to work at all, as it sets all the defaults and the configurations

[stuartpreston]

postimport.ps1 is still being run, I just took out the Linux specialism and converted the paths so it should import on all 3 platforms. I think there's then problems with the New-Json function but that's a bit after this import problem.

[SQLDBAWithABeard]

You are right and I can't read :-)
I have no idea what I saw - Apologies

[SQLDBAWithABeard]

Yes I have to fix some paths on those other functions

[SQLDBAWithABeard]

@stuartpreston I have updated a few other files as well
Thank you very much for the prompt
Its odd that only these files were the ones that fell over publicly
May you test this please to see if it imports

[SQLDBAWithABeard]

and I have added the PR workflow so that it will run the tests too :-)

because I cant read

Convert-Path shouldn't be required to support PowerShell on Mac or Linux.
