Feature: Add .devcontainer to standardize and automate the contributor environment

[Ayushmore1214]

Hey team! I saw the contributing docs mention adding Codespaces support. so I wanted to open an issue to track adding a .devcontainer to the repo. Right now, getting a local environment running means manually installing Go, Node, kubectl, setting up a local Docker registry, and fetching dependencies. Implementing a standardized .devcontainer with Docker-in-Docker (DinD) would let contributors instantly spin up the project in VS Code or GitHub Codespaces. They could immediately run make up/local-cluster

Let me know your thoughts.

What would you like to be added:

That is a cool idea 👍 I happy to have this. In fact, I just changed my PC and feel tired of installing all dependency for the project as well 😂

Yes, sounds like a good idea @Ayushmore1214
