Python: AzureAI Agent int test update to pass

[moonbox3]

Motivation and Context

The AzureAI Agent code interpreter is failing when asking it to use the code interpreter to create bar charts. Updating the unit test so that it uses the code interpreter and doesn't fail/block.

Description

Update integration test while trying to understand the root cause of the failure.
