fix: DatePicker year selection not working with component within EditForm

[msb-incom]

🐛 Bug Report

When using a DatePicker within an EditForm, selecting a year using the year-view of a DatePicker will default to the current year. This does not happen when using the DatePicker outside an EditForm.

💻 Repro or Code Sample

This can be seen in the example on https://www.fluentui-blazor.net/Forms

🤔 Expected Behavior

After selecting a year, I would suspect the date to change to DateTime(year, 1, 1) and to open the month view for the selected year.

😯 Current Behavior

When selecting e.g. "2026"

.. you will return to current date:

🔦 Context

In the current state, the users of my application are unable to use the year-view in the DatePicker.

🌍 Your Environment

• OS & Device: Windows
• Browser: Microsoft Edge, Google Chrome
• .NET and Fluent UI Blazor library Version: 8.0.2 and 4.7.2
