Create a Tour Finder single-page app to demonstrate REST access. See MGNLDEMO-34

• Choose a technology (Angular, React, Vue...). Team can decide.
• The criteria fields should ideally be part of the frontend app (rather than rendered by magnoila) to more completely demonstrate the single page app use-case.
• Use JavaScript to call the REST endpoint done in MGNLDEMO-236
• The tour tiles/cards should be rendered by the frontend app - ie using Angular components if the chosen technology is Angular
• Integrate the single-page app to Magnolia
  • Create a Magnolia template for the Tour Finder page
  • Add the Tour Finder item in the navigation menu
  • Navigation item has an icon in front of it which is different from other menu items. Needs a template.
