Prerequisites

• Write a descriptive title.
• Make sure you are able to repro it on the latest released version
• Search the existing issues.

Steps to reproduce

1. Register an authenticated Azure DevOps Artifacts PSResourceRepository that has the PowerShell Gallery configured as an upstream source. Use the Microsoft.PowerShell.SecureVault module as the source of credentials.
2. Unregister the PowerShell Gallery resource repository.
3. Install-PSResource PSWindowsUpdate

Expected behavior

The `PSWindowsUpdate` module and any dependencies are installed.

Actual behavior

The install appears to work, but the following warning is shown:

> WARNING: Installing dependencies is not currently supported for V3 server protocol repositories. The package will be installed without installing dependencies.

Start by reproducing the authenticated Azure DevOps PSResourceRepository scenario with Install-PSResource PSWindowsUpdate on the reported PSResourceGet and PowerShell versions. Trace the V3 repository dependency-installation path and its warning; done means the module and its dependencies install without that warning.
