Create new top-level "overview" section in docs, note lack of collab support in JLite

• Overview section
  • Add page: "What is JupyterGIS?"
  • Move the "features" section from the user guide to the overview.
    • Move the "how-to setup up collaboration" instructions to a new how-tos section in the user guide. Cross-link.
