a minor fix to structured_output example for running on window OS

[yzhao244]

Description

This PR resolves a permission error that occurs when running the structured_output.py example on Windows operating systems.

Type of Change

• Bug fix

Motivation and Context

When executing the multimodal example on Windows, a PermissionError: [Errno 13] Permission denied is encountered. This occurs because the code attempts to open the same temporary file twice simultaneously - once through the NamedTemporaryFile context manager and again with open(person_file.name, "rb").

Windows operating system enforces exclusive file access, preventing multiple handles from accessing the same file concurrently. This restriction causes the second file opening operation to fail with a permission error.

Adding delete=False to the NamedTemporaryFile constructor resolves this issue by allowing the file to remain accessible after the initial context manager releases its handle.
