feat: Add ContentAi configuration entity to the API Service

[rachel-kittens]

Updates the API Service to support ContentAi configuration through the following changes:

• Added Node version configuration for the project to ensure compatibility
• Added ContentAi configuration to schema for the content AI services
• Updated ContentAi configuration references in schema and tests to ensure proper validation

Testing

• Updated tests to verify ContentAi configuration handling

• Ensured all existing tests pass with the updated dependency locally by updating the dependency on spacecat-shared-data-access to use a version that includes the contentAiConfig property.
  Modify the package.json dependency:

  // From:
  "@adobe/spacecat-shared-data-access": "2.13.1",
  
  // To:
  "@adobe/spacecat-shared-data-access": "https://gitpkg.now.sh/adobe/spacecat-shared/packages/spacecat-shared-data-access?55e76011f10307104381ac3a22b91e249df22112",
