Serve rendered content from tmpfs for local dev

You can run:
 make docker-serve

to run Hugo in a container, building the site and then serving it.

Rather than write the rendered content into the repository for this,
set up a tmpfs and write the content there, then serve it.

This change is also compatible with podman.
