This PR:
- puts the fib3r demo into a dedicated component
- adds routing to the playground, so we can have additional pages
- extracts the json editor, footer, and provider switcher into common
components, which are displayed on every route
- fixes and existing bug where the tour isn't automatically advanced
when json changes are made
- updates to nx 16
The demo functions exactly the same except the footer color no longer
changes (since it's now a "meta component" displayed on every demo.
