Update TypeScript SDK documentation to include --deep flag

Added the --deep flag to all fern generate commands for TypeScript SDK
generation throughout the documentation. This flag is required for the
latest CLI version to properly generate TypeScript SDKs.

Updated files:
- TypeScript quickstart guide
- TypeScript npm publishing guide
- GitLab CI/CD configuration
- Example typescript-publish.yml workflow
