Support descriptions for oneOfType values

[cangoektas]

Hi there 👋

I was digging through the code looking for ways to annotate propType values and found out that (luckily!) there's already support for that. As far as I can see, propType values can be annotated for values of:

• arrayOf
• objectOf
• shape

What do you think about adding support for oneOfType to that list? I'd also like to work on that if there's not a strong argument against it 🙂

Update

Whoops! Sorry, I think I misread the current state. Nested descriptions currently seem to be only supported for properties of shape, like this:

{
  icon: PropTypes.shape({
    /** Name of the icon */
    name: PropTypes.string
  })
}

Now, to be a bit more specific, what I would like to enable is the following:

{
  icon: PropTypes.oneOfType([
    /** Name of the icon */
    PropTypes.string,
    /** Icon element to render */
    PropTypes.element
  ])
}

What do you think?

Sorry for the vague description! Just updated the issue with an example. 👍
