Domain Admins require full permissions to network share to run the script

The documentation is slightly incorrect - it says that for the Network Share, it is sufficient for Domain Admins to have Change permissions. This is incorrect - the user running the script requires Full Control.

Running DeployGPO.ps1 as a Domain Admin with only Change permissions (instead of Full Control) results in:

```
Remote path \\contoso.com\Deployment\Azure Arc Servers Onboarding found!
