Unable to register Azure DevOps feed using Register-PSRepository

[stuartluscombe]

PackageManagement: 1.4.6
PowerShellGet: 2.2.3
PowerShell: 5.1

When trying to register an Azure DevOps artifact feed as a PowerShell repository as per the guide at https://docs.microsoft.com/en-us/azure/devops/artifacts/tutorials/private-powershell-library?view=azure-devops I keep getting errors during the registration.

Steps to reproduce:

Publish a PowerShell module to an Azure Artifact feed
Create a PAT with READ access only
Create a PSCredential object with your Azure DevOps e-mail and the PAT as username/password.
Try to register the feed using an elevated terminal

I've encountered the same issue when trying to publish a powershell module to an azure devops feed.
