Good First IssueWidget: DatePickerfeature request

描述

Is your feature request related to a problem? Please describe. Currently I believe we can't set the hint as we want. We only able to change it by overriding the word using these strings res

<string name="mtrl_picker_text_input_year_abbr" tools:override="true">y</string>
<string name="mtrl_picker_text_input_month_abbr" tools:override="true">m</string>
<string name="mtrl_picker_text_input_day_abbr" tools:override="true">d</string>

but we need to follow the defined format dd/mm/yy.

Describe the solution you'd like It would be nice to have if we can set the custom hint as we want maybe from dd/mm/yy to Day/Month/Year

Describe alternatives you've considered Set the string res that won't printed as double word i.e I put d it will become dd, if I want to put Day it will printed as DayDay.

研究方向
Investigate the DatePicker component in the material components android library, specifically the text input hint mechanism. Look at the current implementation in the `DatePicker` class and the associated layout XML files (e.g., `mtrl picker text input date.xml`). Understand how the hint string is constructed from the string resources `mtrl picker text input year abbr`, etc. Consider adding a new attribute to allow custom hint format, such as a `app:dateInputHint` in the DatePicker's XML or a method like `setDateInputHint(String)`. Also check existing similar features in the library for guidance. The issue number is #2146 and there are no comments or PRs yet, so ensure any proposed change is backward compatible with the default behavior.
