Update Ansible deployment to allow for unprivileged deployment using Podman

- change Ansible collection from community.docker to containers.podman
- update all Ansible tasks to use podman instead of docker, we install podman-docker for a docker compatible CLI but we need to be podman specific in our Ansible playbook
- move group_vars/reductionist -> group_vars/all so all "reductionist_" prefixed vars can be used across plays, specifically Step and Reductionist
- update documentation
