feat(steami_config): Update show_config example with all config features. (#353)

* feat(steami_config): display all config fields  in show_config.py

* style(steami_config): Add blank lines between functions in show_config.

* refactor(steami_config): Extract demo data to populate_demo_config.py.

* fix(steami_config): Rename Raw JSON section to Raw data in show_config.

* docs(steami_config): Add populate_demo_config.py to README examples table.
