title: How to add built-in function (gettext) to pyright?
body: <p>I have a python project with gettext. And I use <code>gettext.install</code> for adding <code>_</code> to built-ins, so it works correctly. But my pyright always shows error: <code>_ is not defined</code>. How can I let pyright know this function?</p>
  <p>My <code>pyrightconfig.json</code>:</p>
  <pre><code>{
      &quot;venvPath&quot;: &quot;.&quot;,
      &quot;venv&quot;: &quot;env&quot;
  }
  </code></pre>
