Fixes #11389 (agent_react_multimodal_step.py bug)

[mjschock]

Description

Explicitly declares the keyword variables for the _add_user_step_to_reasoning call in the MultimodalReActAgentWorker _run_step and _arun_step since the use of a partial was resulting in interpreting the first argument as the generate_chat_message_fn function.
