Variables/Connections/Pools specified in airflow_settings.yaml can't be imported or exported with Podman

[joaomsa]

Describe the bug
Values in airflow_settings.yaml are not respected when using podman as the container binary

When trying to use the astro dev object import or astro dev object export commands while running with podman the commands fail without displaying any error messages.

For the first command, although astro indicates that variables have been successfully imported, the airflow command was never actually run. For the latter we have a fatal error.

These astro commands do not respect the container.binary: podman option specified in the .astro/config.yaml file and instead hardcode the docker executable.
