[docs][pigment-css-react] Warning: React does not recognize the alignItems prop on a DOM element

[abriginets]

Steps to reproduce

Steps:

1. Import Stack from @mui/material-pigment-css/Stack
2. Add alignItems="flex-end" property to it
3. Observe the Warning: React does not recognize the alignItems prop on a DOM element message in terminal

Current behavior

React allow setting any prop and will translate it into real DOM, thus adding non-existent alignItems attribute to div triggers this warning

Expected behavior

Docs should mention this breaking change. I suppose now any styles defined as props should be migrated to sx prop for pigment-css to extract?

Wasn't really sure where to post this issue and decided to put it at the source since @mui/material-pigment-css/Stack simply re-exports pigment-css/react's Stack

Context

Migrating to MUIv6 + pigment
