In updating the types in Bug 1991104, we found that declaring a JSDoc description on a property in our custom elements don't show up on that element's Args Table in Storybook. We should fix this so we can declare JSDoc descriptions in a single spot.

In updating the types in Bug 1991104, we found that declaring a JSDoc description on a property in our custom elements like the following don't show up on that element's Args Table in Storybook. 


```js
export default class MozMessageBar extends MozLitElement {
  constructor() {
    super();
    /**
     * The description for message property here!
     * @type {string}
     */
    this.message;
  }
}
```
