feat(examples): add example-with-typeorm (#8143)
This pull request introduces a new typeorm-service package to the
official TurboRepo examples. The aim is to demonstrate the
implementation of a robust service layer using TypeORM with a custom
dependency injection (DI) mechanism. This example is designed to help
developers integrate a more structured backend architecture with their
existing Next.js applications, leveraging TypeORM for ORM capabilities.
