feat: Enhance image agent with additional runtime context properties

- Added 'aspectratio' and 'numberOfImages' to ImageRuntimeContext type.
- Updated instructions in imageAgent to utilize aspect ratio and resolution from runtime context.
- Configured image provider options to include aspect ratio and image size settings.
