Fix issue #5609: Use litellm's modify_params with default True

[openhands-agent]

This pull request fixes #5609.

The PR successfully addresses the core issue by implementing modify_params functionality in OpenHands with appropriate defaults and evaluation handling. Specifically:

1. The parameter was added to LLMConfig with a default value of True, matching the requested behavior
2. A special case for evaluations was implemented through get_llm_config_for_eval that sets modify_params=False, addressing the concern about benchmark accuracy
3. The implementation includes proper documentation and is integrated across the necessary files
4. All tests and pre-commit hooks are passing

The solution elegantly handles both the default case (True for normal usage) and the evaluation case (False for accurate benchmarking) while maintaining code quality standards. This matches the original issue requirements of:

• Setting modify_params to True by default
• Adding it to the config
• Handling the special case for evaluations where message accuracy is critical

The PR is ready for review and appears to fully resolve the reported issue.

This actually LGTM! But wanted @enyst to take a look. Something i'm not super happy with is the addition function get_llm_config_for_eval. I think we can just merge it with get_llm_config_arg and create an additional evaluation=False kwargs for get_llm_config_arg. When evaluation=True, we hard code modify_params=False inside the existing get_llm_config_arg

@openhands-agent Read this PR, and the file config.template.toml. As you can see, it's a file where we try to document a bit our configuration options. Add the new option there.

Some changes don't appear equal to others.

@openhands-agent Check the diff of this PR carefully. Some of the changes to evaluation run_infer.py files are correct, but others are loading the llm_config twice. Check carefully and fix it.

Overview of Changes:

Status: UNRESOLVED ❌

Key Points:

• Issue: Double loading of config in some run_infer.py files
• Proposed Solution: Remove redundant config loading
• Current Status: No evidence of actual code changes provided

Remaining Issues:

1. Need to see actual code modifications
2. Cannot verify removal of redundant config loading
3. Cannot confirm proper single config load implementation

Next Steps:

• Remove redundant config loading code
• Verify config loading occurs only once with evaluation=True

Recommendation: Request actual code changes for proper verification and resolution.

OK, now it's fine. Started a swe-bench run of an instance and it works as expected.
