Update README for distinct sections for Docker and Podman

[cdolfi]

The readme in the current state can be difficult to follow and parse hoping between docker and podman. This is issue is to put a pin it for it to be updated, if not with distinct sections then figuring out a clear way to convey the information. Another thing to note is that the Build and run section only gives the commands for docker (familiar that it is just a switch for docker to podman in all of the commands but not assumed that the person reading it knows that)
