Determine requirements for making the site public

[mccalluc]

When everything here is completed, DNS for registry.opendp.org can be set up and the project can be publicized.

Software:

• The main branch here is updated with the code behind https://registry.staging.oblivious.com/
• Make this repo public
• CI: Check links #8

Get sign offs:

• Clarify what Salil is being asked to review
  • Get Salil's review
  • Add new action items to this list, if necessary

Documentation:

• Document contribution process
  • For contributors: Point to the file to make a PR against?
  • For admins: When a PR comes in, what is the process?
• Document deployment process: If not github actions, where is it configured, and who is the admin? If the trigger is anything other than an update to main, explain.
• Add a license file at the top of the repo, Should this be a CC license? #1

QA:

• Fix banner links: How to Cite and Contribute currently go to unstyled versions of the page
• Fix citations: Floating commas, missing links, "undefined", etc.

Content:

• Fill in or remove missing authors.
• "zero concentrate" -> "zero-concentrated"
• Remove sections with no content, or fill in:
  • Case Studies
  • Towards Responsible Use
  • Contributions
  • Reviewers
