Remove _Dependency once StreamJsonRpc adds a build target for net472

currently src\Setup\DevDivInsertionFiles\DevDivInsertionFiles.csproj contains following

```
      <_Dependency Remove="Nerdbank.Streams"/>
      <_Dependency Remove="System.IO.Pipelines"/>
      <_Dependency Remove="System.ValueTuple"/>
```

because StreamJsonRpc supports 472 and missing build target for it. once build target is added, we should remove the dependencies.
