Update for ruby 3.2

[ctubbsii]

• Attempt to update for ruby 3.2 again (after ASF INFRA-27632 has been completed)
• Also update README and switch to more vendor-neutral OCI standard Containerfile with podman as the reference command instead of docker

Theses changes look good and I was still able to build/run via docker with

docker build -t webdev -f Containerfile .
docker run -it --rm -v "$PWD":/mnt/workdir -p 4000:4000 webdev

I am not familiar with podman. Install was easy, just installed and set

  [registries.search]
  registries = ["docker.io"]

in /etc/containers/registries.conf after getting an error with podman build

I'm fine with this switch to podman but am just curious what is the main motivation for this change?

Mainly, I use podman instead of docker. But overall, I thought it was nice to move away from the vendor-specific file to a more OCI-compliant one.

I'm curious if the :Z has any impact on docker users, though, or perhaps if it has any impact on users without SELinux. It would be nice if docker behavior worked the same as podman, and if it was completely ignored on something like Ubuntu, without SELinux. Was it necessary to remove the :Z or did you just omit it as unnecessary?

Yea it looks like running the podman command with docker runs just fine: docker run -i -t --rm -v "$(pwd)":/mnt/workdir:Z -p 4000:4000 webdev. From what I can gather, on my Ubuntu-based (Pop!_OS) machine, the :Z is just ignored. So the run command from the README seems to work interchangeably with docker and podman (at least from my machine).
