Add "Enum" IntelliSense for "oneOf" and similar

[Arno500]

🙋 feature request

It would be awesome if the extension scanned "oneOf" types in props, to provides IntelliSense with Enumeration-like propositions (like TypeScript ones).

🤔 Expected Behavior

For these propTypes, when entering "size=" it should start displaying 'small', 'medium' and 'large' for example similar to this one :

😯 Current Behavior

Currently it doesn't do anything on the value side of things.

💁 Possible Solution

Probably in the VSCode extension API ;)

🔦 Context

When having a component that require a certain set of values in props, it is really useful to know what can they be, instead of checking into the component manually.

💻 Examples

Look in the upper sections.
