Stage UI Demo Content

[MitchellShiell]

To Do:

• [x] Fix grid layout
• [x] Update and compress images following demo portal exploration page updates
• [x] Review edit and fix typos and typography in figures
• [x] Update Footer CTA Links
• [x] Match CSS to documentation styling
• [x] Added notebox!
• [x] update formatting of content to be more readable
• [x] fix padding/margins between image title and text
• [x] Create public API key
• [x] add public key to this branch
• [ ] Test Public Key
• [x] Update download dropdown instruction link (may be easier to update documentation pages with demo variable information, the SPA about this portal does not have urls linking specific pages.. yet)

as discussed offline, performance will be improved once compressed images are implemented
