title: Can I set nullable context in `omnisharp.json`?
body: <p>I am using vscode C# extension to manage a few csx scripts.</p>
  <p>It is lightweight, only requires <code>omnisharp.json</code> as config (no need of <code>.csproj</code>)</p>
  <p>However, by default it doesn't enable nullable context even though I have</p>
  <pre class="lang-json prettyprint-override"><code>    &quot;script&quot;: {
        &quot;enableScriptNuGetReferences&quot;: true,
        &quot;defaultTargetFramework&quot;: &quot;net6.0&quot;
      }
  </code></pre>
  <p>I know I can simply add <code>#nullable enable</code> at the top of csx. But I am wondering if there is a way to toggle it via the <code>omnisharp.json</code>. Something like <code>&lt;Nullable&gt;enable&lt;/Nullable&gt;</code> in <code>.csproj</code></p>
