[fix-finder] Add XML documentation to DatePickerDialog.UpdateDate(DateTime)

[github-actions]

Problem

The hand-written, .NET-friendly overload DatePickerDialog.UpdateDate (DateTime date) in the shipped Mono.Android.dll has no XML documentation. It is a public API developers consume, and lacks a <summary> and <param> describing its behavior (it converts the .NET DateTime to Android's year/month/day form, adjusting for Android's 0-based month).

Location

• File(s): src/Mono.Android/Android.App/DatePickerDialog.cs
• Line(s): 33-36

Current Code

public void UpdateDate (DateTime date)
{
	UpdateDate (date.Year, date.Month - 1, date.Day);
}

Suggested Fix

Add /// XML documentation directly above the method:

/// <summary>
/// Sets the current date shown by the dialog using a <see cref="System.DateTime" />.
/// </summary>
/// <remarks>
/// This is a .NET-friendly overload that forwards to
/// <see cref="UpdateDate(int, int, int)" />, converting the 1-based
/// <see cref="System.DateTime.Month" /> to Android's 0-based month value.
/// </remarks>
/// <param name="date">The date to display in the dialog.</param>
public void UpdateDate (DateTime date)
{
	UpdateDate (date.Year, date.Month - 1, date.Day);
}

Guidelines

• Follow dotnet/android formatting conventions (tabs, space before ().
• This is a purely additive, documentation-only change; do not alter any behavior.
• See the Android reference for DatePickerDialog.updateDate).

Acceptance Criteria

• UpdateDate (DateTime date) has a <summary> and <param> XML doc comment.
• No behavior changes.
• All tests pass
• No new warnings introduced
