Boolean default value not showing up in Addon-docs prop table

Describe the bug When using addon:docs prop table for React tsx components the boolean default values don’t show up in the table.

To Reproduce

1. Follow this guide
2. Add some boolean prop like this:

import React, { FC } from "react";

interface ButtonProps {
  /**
   * Simple click handler
   */
  onClick?: () => void;
  /**
   * Is primary?
   */
  primary: boolean;
}

/**
 * The world's most _basic_ button
 */
export const Button: FC<ButtonProps> = ({ children, onClick }) => (
  <button onClick={onClick} type="button">
    {children}
  </button>
);

Button.defaultProps = {
  primary: true
};

1. Run yarn storybook and see the result.

Expected behavior Default values showing up.

Using “@storybook/react”: “^6.5.13” and ran into the same issue 😅

args: {
    defaultChecked: false,
    checked: false,
  },
  argTypes: {
    checked: {
      defaultValue: 'indeterminate',
      options: [false, true, 'indeterminate'],
      control: { type: 'inline-radio' },
    },
    defaultChecked: {
      defaultValue: false,
    },
  }

I had to display those as inline radio so at least it shows wich option is select by default
