Add index page for local preview (#432)

Added a new index page that can be used as the `start_page` in the
preview playbook.

The page uses the same style and path as the Create Applications page at
neo4j.com/docs/create-applications/.

This ensures that localhost:8000 returns a useful page when building
local and PR preview.
