Add DateOnly Json Converter

[totpero]

Related to this #6643 issue, the same is if you have DateOnly property in BackEnd and you want to send Date from FrontEnd.
You need to add also DateOnlyJsonConverter like this:

public class DateOnlyJsonConverter : JsonConverter<DateOnly>
{
    public override void WriteJson
        (JsonWriter writer, DateOnly value, JsonSerializer serializer)
    {
        writer.WriteValue(value.ToString("O"));
    }

    public override DateOnly ReadJson
    (JsonReader reader, Type objectType, DateOnly existingValue,
        bool hasExistingValue, JsonSerializer serializer)
    {
        var v = reader.Value;
        if (v == null)
        {
            return DateOnly.MinValue;
        }

        var vType = v.GetType();
        if (vType == typeof(DateTimeOffset)) //when the object is from a property 
            //in POST body. When used in service, 
            //better to have 
            //options.SerializerSettings.DateParseHandling = 
            //Newtonsoft.Json.DateParseHandling.DateTimeOffset;
        {
            return DateOnly.FromDateTime(((DateTimeOffset)v).DateTime);
        }

        if (vType == typeof(string))
        {
            return DateOnly.Parse((string)v); //DateOnly can parse 00001-01-01
        }

        if (vType == typeof(DateTime)) //when the object is from a property 
            //in POST body from a TS client
        {
            return DateOnly.FromDateTime((DateTime)v);
        }

        throw new NotSupportedException
            ($"Not yet support {vType} in {this.GetType()}.");
    }
}
