[Android / iOS ] Native DatePicker and CalendarDatePicker flyout opens 100 years in the past instead of today

[KikkoMax]

Current behavior

Native date picker on Android and iOS opens 100 years in the past by default.

Calendar date picker opens 100 years in the past for iOS by default.

Expected behavior

Calendar flyouts should open with today as the default date.

How to reproduce it (as minimally and precisely as possible)

1. Build and start app
2. Open native date picker
3. Observe year is 1925 instead of 2025
4. Open managed date picker
5. Observe correct behavior, year is 2025
6. Open calendar date picker
7. Observe year is 1925 instead of 2025 for iOS, but 2025 on android

@MartinZikmund I am re-opening this issue as I am still able to reproduce it with latest Uno.Sdk 5.6.36 for the CalendarDatePicker for iOS.

*(For managed DatePicker I also noticed a separate issue for iOS, which will be tracked with #19567)
