Add resources page

We would like to add a resources page to the website. The page should include:

• Thumbnail image
• Link to the PDF
• Short description about the document
• Grouped by content types that align with the deliverables plan categorization:
  • Documentation
  • Inputs & contributions
  • Whitepapers
  • Specifications

I know we have previously managed these through the newsroom, however the newsroom doesn't allow for descriptions or these categories, so I'm open to either hardcoding this page or updating the newsroom functionality. We need this page by the end of summer, so let us know what option is better. And if we are hardcoding, do we need a design?
