Create a tutorial comparing flox and Docker/container workflows

[zmitchell]

Most developers understand the container lifecycle:

• Create a Dockerfile
• Build software that will live inside the container
• Build the container
• Publish the container
• Run the container using a container runtime

We can compare and contrast that with a flox workflow to better explain how to make use of our software:

• Create one or more project environments
• Make the build(s) work
• Publish the artifact(s) to a catalog
• Create a managed environment
• Install the artifact(s) to the managed environment
• Activate the managed environment
• Run software in the managed environment
