Figure out why Linux and macOS get different hashes

[HowardWolosky]

For some reason, calling Get-SHA512Hash from Helpers.ps1 is returning back different results on macOS and Linux vs Windows. Had to disable the ./templates/verify-testConfigSettingsHash.yaml check on those OS's as part of #181 until that can be better understood.

This means that the check in Tests\Common.ps1 that verifies you've modified the test settings configuration may not be working correctly on those platforms.

Hi @HowardWolosky, you are hitting the age old Windows/Linux crlf vs lf issue on the Setttings.ps1 file. If you force the file to be checked out by Git with crlf eol markers using a .gitattributes file, you will get consistent sha values. More details here: Configuring Git to Handle Line Endings.

I've tested this on the CITest branch of my forked copy of the repo.

Here is the Azure Pipelines Run showing verify-testConfigSettingsHash running successfully on Windows, Ubuntu and MacOS.

@X-Guardian - Thank you so very much! What a completely thorough response and solution. I've added that fix to my PR for trying to completely fix the CI build (#183). The only thing blocking that PR now is determining why there are 7 tests that fail in CI build not locally.
