[docs] Create a doc example to play with the various row selectors

[flaviendelangle]

Summary 💡

Add a playground in the doc where users can plan with the filtering / sorting / pagination etc... and see the impact of the various row-based selectors.

This is a first draft of what can be done.
I don't know which output format would be the easier to read.

Motivation 🔦

We have several selectors that return the rows after the sorting, after the filtering, after the pagination etc...
As we add complexity to the grid, it can be difficult for users to keep track of which selectors can be used for which purpose.

@flaviendelangle @joserodolfofreitas From #4151 I noticed that there are too many combinations to display all the selectors, then I made a component to define the wanted selector according to the features applied

If you have feedback about this first draft, if it is usable, or if there is too much information:
https://codesandbox.io/s/datagrid-v5-quick-start-forked-o57xwi?file=/src/App.tsx

For now, the returned ids are not obtained by selectors, and "tree structure"/"pagniation" are not dynamically applied to the grid (it's in the toto)
