fix: ensure openssh-server is installed and starts

`install_and_run_sshd` previously failed as the base Airflow images do
not include the default ubuntu package repositories. As such, the
openssh-server package could not be found.

Additionally, the ssh_host_keys generated by sshd are owned by root.
This causes permission related failures since the container runs as user
airflow.
