Update collection sources, maintenance #339

As a maintainer I need to review and update the existing repo documentation and align it with recent updates in the 2.5.0 release around enhanced collections.

Acceptance criteria

• Collections that should be contained

  • PF API
  • Component Schemas
  • AI Handbook

• Usage/architecture/development documentation or a new file location like docs/collections.md is updated/added with

  • references to the various collections
  • possible links
  • where the data is sourced from
  • level of maintenance required

Assumptions and questions

• API needs to be documented on the plans to replace aspects of the existing docs.json file

• Component-Schemas may need an indication of planning around API integration

• AI-Handbook source and maintenance
