URL: https://github.com/apache/airflow/issues/34958
### Apache Airflow version
2.7.2
### What happened
Hi Guys,
All our dags which use the PythonVirtualEnvOperator and call a python
function using python_callable param, they fail due to FileNotFoundError for
the tmp_dir/script.out file.
Can someone explain why this is happening and what is expected for the
script.out file? Is the python function supposed to print or return someting to
write into the script.out file?
```
Executing cmd: /tmp/venvx9cl8fpi/bin/python /tmp/venvx9cl8fpi/script.py
/tmp/venvx9cl8fpi/script.in /tmp/venvx9cl8fpi/script.out
/tmp/venvx9cl8fpi/string_args.txt

```
### What you think should happen instead
It seems that the PythonVirtualEnv operator class expects mandatory
arguement for output file directory containing 'script.out'. This behaviour is
not happening in PythonOperator but we have to use the Virtual env operator to
pass specific python requirements also. What needs to be passed here -
https://github.com/apache/airflow/blob/main/airflow/operators/python.py#L426
### How to reproduce
Create DAG which calls Python script using PythonVirtualEnv operator. DAG
fails expecting 'script.out' file to be present in directory.
