fix(pwsh): replace Get-Error with $error[0] (#2873)

Browse Source 
Get-Error does not exist in all versions of PowerShell, and attempting to use it on machines where it does not exist pollutes $error. Someone may be tempted to use -ErrorAction Ignore but since the command does not exist, it still ends up in $error

This is a dual bug fix because it actually gets errors on all machines now and it does not pollute $error.
