Labels: framework,f: material design,f: date/time picker,P2,team-design,triaged-design

### **Update**


**Bug is fixed in https://github.com/flutter/flutter/pull/131253, token update is pending**

-----------------------

### Is there an existing issue for this?

- [X] I have searched the [existing issues](https://github.com/flutter/flutter/issues)
- [X] I have read the [guide to filing a bug](https://flutter.dev/docs/resources/bug-reports)

### Steps to reproduce

TimePicker's `hourMinuteTextStyle` should be using `TextTheme.displayMedium`, instead it uses `TextTheme.displayLarge`.

However, the token in the `time_picker.json` file is incorrect or outdated. This causes a bug in the input mode. (desktop and mobile)
