title: PyCharm not generating docstrings and no settings under Python Integrated Tools
body: <p>I'm trying to generate the docstrings to document my python functions, but when I'm going to</p>
  <p><code>PyCharm</code> <code>&gt;</code> <code>Settings</code> <code>&gt;</code> <code>Tools</code> <code>&gt;</code> <code>Python Integrated Tools</code></p>
  <p>I find an empty window with no options and in particular no <code>Docstrings</code> <code>&gt;</code> <code>Docstring format</code> <code>&gt;</code> <code>reStructuredText</code> which is what I need to configure the docs format as my colleagues.</p>

  <p>In addition when I click on the lightbulb near the function name and click on &quot;Insert a documentation string stub&quot; nothing happens.</p>

  <p>Is there a way to fix this? I'm using <code>PyCharm 2021.1.1 (Professional Edition)</code> on macOS.</p>
