[glen-84]

Summary of the changes (Less than 80 chars)

• Moved LocalDate/LocalTime to HotChocolate.Types and added LocalDateTime.

Closes #6420

---

LocalDate and LocalTime scalars moved

LocalDate and LocalTime have been moved from HotChocolate.Types.Scalars to HotChocolate.Types, and are therefore available without installing the additional package.

DateOnly and TimeOnly binding change

• DateOnly is now bound to LocalDateType instead of DateType.
• TimeOnly is now bound to LocalTimeType instead of TimeSpanType.
