Documentation: EntitiesSavedStates editor component

What? & Why?

Addresses one item in #60358

Adding documentation to existing editor components can help with any of the following:

• encourages knowledge sharing and quicker onboarding for future devs
• supports maintenance and troubleshooting
• mitigates risk

How?

Add a JSDoc comment to the EntitiesSavedStates component and run npm run docs:build to populate the README with the newly added documents.

While investigating #67313 I noticed the documentation of the renderDialog prop may not be accurate. To me, it seems it's just a boolean flag that switches the component to render some ARIA properties and make it behave like a modal dialog as implemented in #59622
Instead, it's documented as a {Function} to render the modal dialog here, here, and here.

Am I missing something? @colorful-tones @ntsekouras could you please have a look, when you have a chance?

No, it seems you're right. We missed that..

Thanks for the feedback. It will be fixed either in #67351 or #67352 (where renderDialog is removed).
