[docs] Demo QuickFilteringGrid crashes about mui-x HOT 3 CLOSED

thanks @EmilianoLam ... I can confirm this bug.

Steps to reproduce:

1. enter edit mode on rating cell
2. change rating with arrows
3. exits edit mode after first arrow key (<- first bug)

Second bug:

1. enter edit mode on a value 5 or value 1 rating
2. go one up or down to reach value 0 (separate bug from **Rating** component here)
3. demo crashes with following error message (from local dev instance):

react-dom.development.js:22834 Uncaught TypeError: Cannot read properties of null (reading 'focus')
    at handleRef (renderEditRating.tsx:18:68)
    at setRef (setRef.js:20:5)
    at eval (useForkRef.js:24:60)

It seems that there are several problems here:

1. The edit mode stops whenever there is a change
2. the element with value 0 cannot be found
3. unrelated: the Rating component has a bug where pressing arrow down increses the value
