PowerShell setup script fails in Windows PowerShell

[waldekmastykarz]

When you try to run the PowerShell setup script in Windows PowerShell it fails with Unsupported OS . Aborting. This is caused by Windows PowerShell not supporting $PSVersionTable.OS which we use to detect the OS. We need to either update the setup script to use an alternative way of detecting the OS or show a clear error message that Windows PowerShell is not supported and you should use Microsoft PowerShell instead. If we can't support Windows PowerShell, we should also include it in our docs.

Stumbled upon this error this morning, thought it was because I was running it on a virtualised Windows 11 on a MacBook Air (Parallels). OS identifies itself as an ARM version. Tried this approach due to #609

Accidentally made a pr on the original repo, wanted to merge it into my own main first.

Was working on a better pr and then saw you did exactly the same :)
I lowercased the OSDescription because you never know right?

Thanks for the fix!

Sorry I went over your PR: we needed the fix sooner for an experiment that we're running and I didn't want to push you on a our timeline. Once again, thank you for working with us, we appreciate your help.
