Remove warnings suppression for multiprocessing in run scripts

- Eliminated unnecessary warnings suppression related to multiprocessing resource tracking in `run.py` and `run_parallel_simulation.py`, streamlining the code and reducing potential confusion.
- This change enhances clarity in logging by allowing relevant warnings to be displayed during execution, improving traceability and debugging capabilities.
