### Task name

DownloadBuildArtifacts

### Task version

1.220.0

### Issue Description

We noticed that we were using DownloadBuildArtifacts@0 while a @1 version was available. Upgrading, while doing no other changes, lead to the warning:
_Please use Download Build Artifact task for downloading UNC type artifact. https://docs.microsoft.com/en-us/azure/devops/pipelines/tasks/utility/download-build-artifacts?view=azure-devops_

The warning message is a bit strange as we are in fact using the task mentioned and UNC type artifacts!?

Artifact was uploaded using PublishBuildArtifacts@1 which seems to match DownloadBuildArtifacts and no warning was emitted before updating to DownloadBuildArtifacts@1.

We are using Azure DevOps Server so we cannot use PublishPipelineArtifacts/DownloadPipelineArtifacts, but it would be nice to know why on-prem is kept on these older and less optimized tasks. There seems to be few changes between @0 and @1 so I guess that we could revert the change, but wonder if the @0 would be deprecated at some point.

### Repro steps

_No response_

Start at the DownloadBuildArtifacts@1 task entry point and compare its UNC artifact handling with @0. Reproduce the warning using PublishBuildArtifacts@1, a UNC artifact, Azure DevOps Server 2022.1 Update 1, and the provided task version. Done means the warning is emitted only when appropriate and the task behavior is covered by relevant tests.
