Implement get in equivalently to the reference

Implement get in equivalently to the reference: a task in repo2rlenv-equivalence-tests (Harbor dataset). Implement the function get in in /workspace/task module.py so that it is behaviorally equivalent to reference get in (which is already provided in task module.py ).

The task

Implement the function `get_in` in `/workspace/task_module.py` so that it is behaviorally equivalent to `reference_get_in` (which is already provided in `task_module.py`).
