INIT task throws an exception in Windows PowerShell

[TrisBits]

The INIT task throws an exception when called from a Windows Powershell session. This same issue was previously reported in issue #53 and fixed with merge #60. However, the fix seems to have since been reverted causing the issue to return.

Expected Behavior

PowerShellBuild tasks should also be compatible with PowerShell 5.1

Current Behavior

Receive error:
Exception: Method invocation failed because [System.IO.Path] does not contain a method named 'IsPathFullyQualified'.

Possible Solution

Re-implement the fix from merge #60

Steps to Reproduce (for bugs)

1. Create a new module with Stucco
2. Execute .\build.ps1 from a Windows PowerShell terminal

Context

I was attempting to build a PowerShell 5.1 module. Once I modified the Initialize-PSBuild function based on the change in merge #60 it worked flawlessly.

Your Environment

*Module version used: 0.6.1
Operating System and PowerShell version: Windows 10 with PowerShell 5.1
Running .\build.ps1 from the Stucco template

I can reproduce this on my end too, but work in Powershell 7.3.2
