chore(config): add lightspeed notebooks configuration schema

[its-mitesh-kumar]

Description

• Add lightspeed.notebooks configuration schema to packages/app/config.d.ts
• Also added lightspeed.prompts configuration schema to packages/app/config.d.ts which I found missing. Without the prompts schema, custom user prompts configured in app-config.yaml would not be readable by the frontend
