Subject: [PATCH] feat: Introduce Network Module and Basic Network
 Communication

- Implement `NetworkModule` for managing HTTP client with JSON content negotiation.
- Add `kotlinx-serialization-json` and `ktor-client` dependencies for network requests and serialization.
- Implement basic network communication in `Greeting` class to retrieve and display time data from a remote API.
- Add `NetworkResponse` and `TimeResponse` data classes for handling the response from the remote API.
- Refactor the `greet` method in `Greeting` class to integrate network request.
