[Issue] Figure out a good alternate extension to Docker desktop

[jongio]

Some devs won't have docker desktop, so let's figure out an alternative recommendation.

@jongio can we use this issue #509 for tracking the same and close this one?

That one is about docker build only. We should figure out all the dependencies on docker and see what can be replaced by what and then decide.

The most commonly used alternative is Podman, but there are others (e.g. nerdctl). There is also more and more options for building container images directly via programming language-specific build tool, e.g. dotnet just got one recently: https://devblogs.microsoft.com/dotnet/announcing-builtin-container-support-for-the-dotnet-sdk/

Ultimately we might want to tread container build as extensibility point.
