[Bug]: `list` types in functions for tools are failing

[marklysze]

Describe the bug

When a function is converted to a tool it can cause a crash if it has a parameter that is a list.

Raised as an issue on Discord, message link.

The code in this cookbook example is noted as an issue:
https://docs.ag2.ai/latest/docs/user-guide/advanced-concepts/pattern-cookbook/feedback_loop/#agent-flow

The submit_document_plan function has a parameter outline: Annotated[list[str], "Outline points for the document"] and this is causing an error in get_load_param_if_needed_function in function_utils.py.

I did create a PR to fix this but @davorrunje has noted there may be an alternative way as the original code was put in place due to Python 3.8 support, which we have now moved on from:
#1662
