chore(docs): add navigation configuration

The documentation in this repository is added to the overall npm documentation at https://docs.npmjs.com/, which includes both the documentation for the public registry and the CLI. The documentation site itself also has a navigational hierarchy; since the content is included from the CLI, we also want to ensure that the navigation for that content lives in this repository. This means that this repository is the source of truth for all of the CLI documentation, and we do not need to update two places when we add, edit, or remove CLI documentation. It all lives here. This also teaches the documentation rendering script to identify when the navigation configuration (nav.yml) is missing new pages that were recently added or retains old pages that have recently been deleted.
