Subject: [PATCH 1/7] [release/11.0.1xx-preview1] [dotnet] Fix publish BAR
 manifest step

Publishing is currently failing with:

    build-tools\create-packs\Directory.Build.targets(188,5):
    error MSB4062: The "PushToBuildStorage" task could not be loaded from the assembly C:\Users\cloudtest\.nuget\packages\microsoft.dotnet.build.tasks.feed\11.0.0-beta.26064.107\build\../tools/net/Microsoft.DotNet.Build.Tasks.Feed.dll.
    Could not load file or assembly 'System.Runtime, Version=11.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'.
    The system cannot find the file specified. Confirm that the <UsingTask> declaration is correct, that the assembly and all its dependencies are available, and that the task contains a public class that implements Microsoft.Build.Framework.ITask.
    [build-tools\create-packs\Microsoft.Android.Sdk.proj]

`PushToBuildStorage` is now targeting .NET 11, but this is a step that
is using a stable .NET SDK (currently .NET 10).

For now, let's just use a slightly older version of the
`PushToBuildStorage` task that targets .NET 10.

When .NET 10 Preview 1 has shipped, it will be easy to use the
`UseDotNet` yaml task and fix this properly.
