CAMARA Project Admin Update

This pull request adds the new line 13 (API description for marketing) to existing API-Readiness-Checklist.md files to align them with the latest template.

Changes:

• Added line 13: "API description (for marketing)" with appropriate requirements for each release stage
• Inserted after line 12 (Previous public release was certified)
• Maintains proper table formatting and structure

New line added:

| 13 | API description (for marketing)              |   O   |         O         |    M    |    M   |      | [wiki link](https://lf-camaraproject.atlassian.net/wiki/xxx) |

Requirements by release stage:

• alpha: Optional (O)
• release-candidate: Optional (O)
• initial public: Mandatory (M)
• stable public: Mandatory (M)

This ensures all API readiness checklists include the marketing description requirement that becomes mandatory for public releases.
