Silence Ansible devel warning, again (#956)

Silence Ansible devel warning, again

I rebuilt the image fresh and was very annoyed by getting this error running completely unrelated commands in the image
[WARNING]: You are running the development version of Ansible. You should only run Ansible from
"devel" if you are modifying the Ansible engine, or trying out features under development. This
is a rapidly changing source of code and can become unstable at any point.

It turns out that this is silenced in the ansible-galaxy command in the entrypoint.sh script, but the same problem happens again just a few lines down doing ansible --version, and this case is not silenced.
This applies the same method to the second case, so that this will run quiet:
(env) [alancoding@alan-red-hat ansible-runner]$ podman run --rm --tty --interactive --env AWX_ISOLATED_DATA_DIR=/runner/ quay.io/ansible/ansible-runner:devel whoami
