Update dotnet worker's official and public pipelines to trigger tests pipeline

Steps:

• Create a nuget package with the latest changes on worker side.
• Publish the package to a test feed
• Trigger integration tests pipeline to run tests with that nuget package
• Wait for pipeline to complete. If tests pass, publish the nuget package to regular feed.
• Fail the pipeline if tests pipeline fails and do not publish nuget package to the feed.
