Change Bindings and Configuration Quickstarts to allow Podman AND Docker

[artursouza]

Both, Bindings and Configuration quickstarts, refer to Docker CLI commands and do not allow our automation to switch to Podman. It is OK if the pre-reqs mention both but we should fallback to Podman for MacOS validation. It means that our Quickstarts should not invoke podman or docker commands to keep them agnostic.
