[wasm] Fix reference to Microsoft.Build.NoTargets (#75472)

.. in `WasmTestRunner.proj` used for runtime tests.

This project requires an explicit SDK version number because it is used
on Helix, and `global.json` is not available there. The version matches what we
have in `global.json`.

```
  Starting:    Loader.classloader.XUnitWrapper (parallel test collections = on, max threads = 2)
    Loader/classloader/DefaultInterfaceMethods/genericmethods/genericmethods/genericmethods.sh [FAIL]
