Expected behavior 🤔

The generated integer should not exceed the max boundary

Context 🔦

@joserodolfofreitas noticed an issue in our data grid demo at https://mui.com/x/.
Sometimes some of the rows are missing the commodity field and are rendered outside of the groups:

missing-commodity.mov

We use the randomCommodity function for this and it should never return undefined:

mui-x/packages/grid/x-data-grid-generator/src/services/random-generator.ts

Line 119 in 1096705

export const randomCommodity = () => randomArrayItem(COMMODITY_OPTIONS);

This is how I discovered an issue with the randomInt function.
