Host more common package repositories for automated testing with PSResourceGet

[o-l-a-v]

Summary of the new feature / enhancement

PSResourceGet tries to support multiple repositories, but only tests against some of them.

• https://github.com/PowerShell/PSResourceGet/tree/master/test

Add test instance of more repositories so one can make reliable additions and changes to PSResourceGet in regards to other repository systems. Like:

• Azure DevOps
  • Supports NuGet v2 and NuGet v3: https://learn.microsoft.com/en-us/azure/devops/artifacts/nuget/nuget-exe?view=azure-devops#legacy-project-setup
• SonarType Nexus
• JFrog Artifactory

Else issues like #1491 will continue popping up.

Proposed technical implementation details (optional)

• Microsoft owned stuff like Azure DevOps should be easy enough.
• Ask 3rd parties to host public test instances?
• Spin up and take down self hosted repositories as part of GitHub actions / workflows?
  • Will require some CI/CD engineering.
