DatePicker does not recognize dates after year 9999

[eberleant]

Description

The DatePicker in Vaadin 23.2.8 doesn't seem to recognize dates after year 9999. For example, if I type 01/01/10000 in the input, the value in the DatePicker is null. If the field isn't attached to a binder, it will also style itself as invalid.

Might be related to vaadin/framework#11881

Expected outcome

I would expect dates after year 9999 to be treated like any other date (theoretically, up to Year.MAX_VALUE = 999_999_999).

Minimal reproducible example

This can be reproduced with the basic DatePicker demo from the Vaadin docs:
https://vaadin.com/docs/latest/example?path=component/datepicker/date-picker-basic.ts

Steps to reproduce

1. Click the date picker
2. Type "01/01/10000"
3. Press enter

Result: The date picker is styled as invalid and the value is null.

Environment
