What is the justification for these changes?

Why you consider them improvements? Are you against docker compose but a advocate of docker.io?

Thanks @ninos-ego!

I've added a review on the PR. The main push back there is that the one line change explicitly adding Podman as an option could require many more changes to documentation elsewhere across w.org.

A few other concerns after looking this over:

• Any contributor that currently has a docker-compose.override.yml file locally will no longer see their overrides reflected within the environment. This is probably fine and we've made changes in the past that required action (sometimes even recreating the environment completely), but the timing of this change should be calculated and a developer note _may_ be appropriate.
• One possible side effect of this change is that it becomes more difficult for newer contributors to find information on the Internet about how the file works. There are tons of tutorials and resources online that reference docker-compose.yml. Not a blocker, but something we should consider!

Marking for re-check to ensure this is in my list to return to.
