Patching a TodoTask which has a Recurrence value fails

Describe the bug

I am trying to patch an existing TodoTask that has a recurrence value. It loads fine, but when I go to patch it (even with no changes), it results in:
Invalid JSON, Error converting value "2025-09-23" to type 'Microsoft.OData.Edm.Date'. Path 'recurrence.range.endDate', line 1, position 46.

Expected behavior

It should patch the TodoTask without error and set the Recurrence changes.

How to reproduce

TodoTask tdTemp = new();
tdTemp.Recurrence = new()
    {
        Range = new()
        {
            Type = RecurrenceRangeType.EndDate,
            StartDate = new(DateTime.Now),
            EndDate = new(DateTime.Now.AddYears(1))
        }
    };
var result = await GraphClient.Users[MSGraphId.ToString()].Todo.Lists[list.Id].Tasks[task.Id].PatchAsync(tdTemp);

### Other information

Someone else reported it here:
https://learn.microsoft.com/en-gb/answers/questions/806339/unable-to-patch-a-todo-task-with-a-recurrence-patt

Start with the C# GraphClient.Users[].Todo.Lists[].Tasks[].PatchAsync call shown in the reproduction and reproduce it using SDK version 5.58.0. Trace how the recurrence range dates are serialized for the patch request; done means an existing TodoTask with an EndDate recurrence patches successfully without the Microsoft.OData.Edm.Date conversion error.
