Rearrange items in Getting Started navigation (#6126)

Though the subsections are representing features such as navigation and
settings, they are categorized by the ways how they are implemented
(internal navigation or external links.) They are irrelevant and some
arrangements were confusing because of that. (It is nonsense that instance
information is in settings subsection, for example.)

This fixes the issue by rearranging.
