aider: Add shell=True to subprocess.run in cmd_run.

# Aider chat conversation:

USER: add `shell=True` to subprocess.run in cmd_run

ASSISTANT: To add `shell=True` to the `subprocess.run` call in the `cmd_run` method, we need to modify the `aider/commands.py` file. Here's the change:

<source>python
aider/commands.py
<<<<<<< HEAD
            result = subprocess.run(
                parsed_args, stdout=subprocess.PIPE, stderr=subprocess.STDOUT, text=True
            )
=======
            result = subprocess.run(
                parsed_args, stdout=subprocess.PIPE, stderr=subprocess.STDOUT, text=True, shell=True
            )
>>>>>>> updated
</source>
