Better article for binding data to components

[mshabarov]

Tell us about your request

Binding Data to Components article is missing the following:

1. How to bind items to the TreeGrid, in-memory and backend.
2. How to make an add-on to DataProvider, either plain and hierarchical.
3. The article should have a laconic user-friendly name and url, e.g. "Data in Components", "/data-in-components". And this should be a top-level article on the same level as "Forms", because this is 99,9% use case in business applications.

Also can be done together with https://vaadin.com/docs/latest/flow/binding-data/data-provider to add more reasoning around data view concept.
