This fixes the issue where someone specifies `fedora-version: latest`, which won't be known until build-time. I also added a small "welcome" banner to the build log. It's really just there to retain a somewhat contrived use-case example for how to use `get_yaml_string()`, for other programmers who want to extend this in the future.
