Improve instruction string clarity in GetAdditionalJsonResponsePrompt

The commit changes the response string in the GetAdditionalJsonResponsePrompt method. The previous phrasing was potentially unclear, so it has been adjusted to more explicitly require RFC8259 compliant JSON and to remove unneeded verbiage in the examples section. This is intended to improve user comprehension and adhere more strictly to JSON conventions.
