DPG List On Registry Page Uses new Web App API Endpoint

[nathanfletcher]

This PR:

• Refactors the DPG table on the registry page to use the newly built API from the review process Web APP.
• Refactors the build process for deploying the DPG website -The new API has a very different JSON structure for DPGs. All aspects of the build process had to be modified to reflect these major changes to the JSON structure, as it was tightly linked to how the site is built and other components of the DPG website.
• Reduces build time for DPG website deployment
  • Since the new web app already generates a web page for new applications, I have removed the build step, which manually does the build
  • The new review process removes nominees. As such, the build step for nominees on the registry page is also removed.

ToDo:

• Update Data explorer graphs to use only DPGs in the new API
• Update the DPG map to use the new API
