Introduce PODMAN_BACKGROUND_MODE environment variable to control podman run mode
Use --detach flag for background mode and --interactive flag for foreground mode
Update PODMAN_COMMAND to include the appropriate flag based on PODMAN_BACKGROUND_MODE
This change allows the script to conditionally run ilab podman containers in the background or foreground based on the value of the PODMAN_BACKGROUND_MODE environment variable
