WWW: Create Home page

[mjherzog]

This issue covers the design and implementation of the Home page for the new www.aboutcode.org website.
The Home page is intended to provide an overview of AboutCode as a family of projects followed by subsections of project cards in logical groups to provide a summary of the project portfolio - the current count of 44 to feature here.

The Supporters section is a placeholder for now. We may want to move that section to the About menu.

I have attached the file Homepage.md with draft text for the Home page including intro sections for the project cards.
See #61 for information about the evolving project cards.

I have created an alternative layout for the website Menu items. Instead of major projects the top menu items would be functions with use cases. The text would be function-focused rather than project-focused. For example PURL would be referenced almost everywhere, but not as a top-level menu item.

• Software (management?)
  • Identify software components and packages
  • Identify software dependencies
  • Consume and generate SBOMs
  • Match binaries to source
• Security
  • Identify vulnerabilities
  • Triage vulnerabilities
  • Manage risks with aggregated vuln data
  • Report exploitability (VEX)
• Compliance
  • Identify licenses for software and for data
  • Apply usage policies
  • Generate SBOMs
  • Generate compliance artifacts (e.g. attribution notices)

Another top-level menu item could be Risk management.

This is just a first cut list. See also the option-2 worksheet https://docs.google.com/spreadsheets/d/1L1hTaErF8RuKe4nX5LxVifLxoxR3qDHyA-S_r2KKe94/edit?usp=sharing
