[TreeView] `useSimpleTreeViewApiRef` should expose the actual ref to the root DOM node

[yairEO]

Summary

The useSimpleTreeViewApiRef API should expose rootElementRef to get the root DOM node, similarly to what already exist in DataGrid component:

const apiRef = useGridApiContext();
const gridRoot = apiRef.current.rootElementRef?.current;

👉 There is no equivalent for const apiRef = useSimpleTreeViewApiRef();

Examples

No response

Motivation

I need this in order to find & highlight texts using a 3rd-party package react-css-highlight

It is far from ideal to manually create a ref just for that when useSimpleTreeViewApiRef already exists, without any props-drilling required.

Also, the docs are missing a page for explaining the available properties of the apiRef object returned from useSimpleTreeViewApiRef. Would be helpful...
