[Basic] Typing example for objects with a string id

[KitsonBroadhurst]

What cheatsheet is this about? (if applicable)

Basic cheatsheet

What's your issue or idea?

Add an object example to the "Basic Prop Types Examples".

I occasionally find myself in a situation where I have an object which has an id of type string with lots of varieties, but all have the same value.

e.g.

  interface HistoryItem {
    id: string;
    before: string;
    after: string;
  }

  inteface History: {
    [key: string]: HistoryItem;
  }

I always go here to find the reference and then have to google it and end up at this SO question: https://stackoverflow.com/questions/13315131/enforcing-the-type-of-the-indexed-members-of-a-typescript-object/53717982

Happy to PR something.

thanks @KitsonBroadhurst ! yes PR welcome. also dont forget that you can use the official Record<K,T> type to do this - i'd actually recommend that as that is fairly idiomatic typescript
