Describe the bug

When ilab receives a list in a specific way, for example when ilab model train receives the lora_target_modules parameter, Click performs some magic under the hood which automatically converts the list into a tuple.

Oftentimes though this is not behavior which we want, since we naturally expect the specific list data structure
under the hood in many of our type signatures. For example leading to the error which was solved by this PR: #2026

/opt/app-root/lib64/python3.11/site-packages/pydantic/main.py:364: UserWarning: Pydantic serializer warnings:
  Expected `list[str]` but got `tuple` - serialized value may not be as expected
  return self.__pydantic_serializer__.to_python(

To Reproduce
Steps to reproduce the behavior:

1. Check out any commit prior to when Enforce list type for lora-target-modules #2026 was merged (if it's merged by then)
2. Run ilab model train

Expected behavior

No warning message appears
