(docs): update README with new prop definition

- Add the `clearOnResize` definition
- Move `backgroundColor` in the component's prop list to match the docs
  - nb: `backgroundColor` is still not perfectly defined as a prop

- Change introductory language from "differences" to "new, documented"
  as "differences" could imply good and bad changes (e.g. new opinions),
  while "new" has a very different connotation and most API/props
  changes were backward compatible
