[FEAT] Implement a Daffodil docs nav, separate from the marketing portion of the site

💡 Feature request

Feature Name

Daffodil Docs Navigation

The Desired Behavior

The docs section of daff.io top nav should be different from the marketing page nav. This is the tentative structure of what the top nav and primary sidebar should have:

Top Nav:

• Packages
• Design
• API Index (no left nav required)
• Search field

Your Use Case

As a Daffodil core developer, I want the docs.daff.io navigation to be separate from the marketing page nav.

Environment

Daffodil version: 0.66.1
Angular version: 15.2.0

 
For Tooling issues:
- Node version: XX  
- Platform:

This is technically complete since there is a different nav for docs. What's missing is the Design link and search field, which should be handled in separate issues.
