Docs (Theme) Fix Version shortcode (#105)

* remove line breaks in version shortcode

* enhance readability and hardcode master default

fix readability by using the whitespace handling of hugo templates: https://gohugo.io/templates/introduction/#whitespace
provide a master default value if the CURRENT_LATEST_TAG env variable is not set such as running locally with symbolic links to themes and not using the build/local script.
