changes structured temperature to not deadly

[monkeywithacupcake]

Changed the example in structured output snippet to show 22.5 C instead of 72.5 C for logical example.

closes #1327

Motivation and Context

This change only makes the structured output snippet easier for humans to understand seeing how the structure (temperature in Celsius) is consistent with the example value: 22.5 (was 72.5...which is deadly)
