Thank you for your contribution! 🙏

You need to find the file where this string is defined as JSDoc for this given slot and update it only there. In this case it seems that PickersLayout.types.ts is the place.
Running yarn docs:api should take care of updating all the necessary doc "translations" files. 😉
