[release/2.1] Use new packages in RepoTasks.csproj (#20077)

- use Azure.Storage.Blobs v12.10.0
  - WindowsAzure.Storage v8.7.0 brings in packages w/ expired certificates
  - avoid earlier versions because they attempt to bring in Newtonsoft.Json v10.0.2 or later
    - this version eliminates that dependency
    - i.e. don't attempt to override Newtonsoft.Json v9.0.1 used in NuGet.* packages
- react to breaking changes between Microsoft.Azure.Storage.Blob and Azure.Storage.Blobs
  - WindowsAzure.Storage and Microsoft.Azure.Storage.Blob API surface was similar
