Using `Readonly<T>` utility type results in losing pieces of `T`'s information

You can paste the code below in the playground and see that description and tsType are lost.

interface Props {
  /** The name to greet */
  name: string
}

/**
 * Hello world component
 */
const MyComponent = ({name = 'world'}: Props) => {
  return <div />;
}

/**
 * Hello world Readonly
 */
const MyReadonlyPropsComponent = ({name = 'world'}: Readonly<Props>)=> {
  return <div />;
}

I noticed this behaviour while digging through an issue that appeared after the latest Storybook's major update, which uses this package by default to extract information from the components.

Riproduci il problema nel playground collegato usando i due esempi di componenti e confronta i risultati estratti per Props e Readonly. La correzione è completa quando il risultato di Readonly conserva la descrizione della prop e le informazioni tsType mostrate per Props.
