[BUG]: DownloadAsyncV2 downloads to memory instead of disk

[philipborg]

What happened?

While downloading using DownloadBuildArtifacts@1 task it seems to download to memory. That task in turn just calls the DownloadBuildArtifactTaskV1_0_0 plugin located in this repo, hence it's being placed here.

What has been observed is that when downloading a larger file, in our case ~450MB, is that the agent memory usage increases by the download progression exactly and then freezes when it can no longer allocate more memory as those agents only have 1GB of RAM in total. Thus my conclusion is that the code downloads the artifact to memory instead of onto disk.
