Airflow on Podman Not Supporting Other Users

### Apache Airflow version 3.1.7 ### If "Other Airflow 3 version" selected, which one? _No response_ ### What happened? I'm trying to run airflow in a rootless podman installation. I'm finding lot's of trouble with the permissions and have stripped back to what I believe the most basic test of the image. I'm executing the command: `podman run --user=$(id -u):0 docker.io/apache/airflow:3.1.7 airflow version` This pulls the image just fine, but the /entrypoint script does not seem to be setting the python environment correctly for the specified user ``` .................... ERROR! Maximum number of retries (20) reached. Last check result: $ airflow db check Traceback (most recent call last): File "/home/airflow/.local/bin/airflow", line 3, in <module> from airflow.__main__ import main ModuleNotFoundError: No module named 'airflow' ``` I've ran this test on two machines currently, both running Ubuntu server, one of which being a fresh install with the only prior commands being to upgrade apt and install podman. This occurs on the container `airflow:3.1.0` as well but not `airflow:3.0.6` or `airflow:2.11.1` ### What you think should happen instead? This should start the airflow container and report the airflow version in addition to all other items handled in the /entrypoint script. ### How to reproduce 1. Install podman 2. Run basic airflow command with `podman run --user=$(id -u):0 docker.io/apache/airflow:3.1.7 airflow version` 3. Receive python module errors ### Operating System Ubuntu 24.04.4 LTS ### Versions of Apache Airflow Providers _No response_ ### Deployment Other Docker-based deployment ### Deployment details Only tested with podman version 4.9.3 ### Anything else? _No response_ ### Are you willing to submit PR? - [ ] Yes I am willing to submit a PR! ### Code of Conduct - [x] I agree to follow this project's [Code of Conduct](https://github.com/apache/airflow/blob/main/CODE_OF_CONDUCT.md)
