Agree on moving the Pigment CSS examples, but instead of removing the one from Material UI, can we repurpose them on how to set up Material UI with Pigment CSS and popular frameworks? This will be important when v6 is released.

@mnajdova Great idea. Reopening:

• Add /examples/material-ui-vite-pigment-css example, similar to https://github.com/mui/material-ui/tree/8f45c8e5cf55f650bc14e1fad1d87d17228f27a0/examples/material-ui-cra-styled-components in Material UI.

The only counter-argument is that; the sooner we can make Pigment CSS the default what to use Material UI, the better. At which point, we would have the opposite a /examples/material-ui-vite-emotion example.
