Add overview to ChaosCenter Developer Guide documentation

[PriteshKiri]

Description
The ChaosCenter Developer Guide currently lacks an overview section. Adding an introductory overview will help developers understand the purpose, architecture, and scope of the guide before diving into setup and usage instructions.

Location
website/docs/developer-guide/chaoscenter-developer-guide.md → At the beginning of the document

Proposed changes
• Add a new Overview at the top of the guide with the following content:

ChaosCenter is the control plane for LitmusChaos, providing a web-based interface and APIs to manage chaos experiments on Kubernetes clusters. It consists of a backend (GraphQL server, Authentication server, MongoDB) and a frontend (React) component. This guide walks you through setting up ChaosCenter locally, running the required services, and connecting your Kubernetes infrastructure to execute and monitor chaos experiments.

The document assumes a local development environment and is not recommended for production or shared clusters. By the end of this guide, you will have a fully functional ChaosCenter instance capable of managing chaos workflows and integrating with Litmusctl or ChaosCenter-managed infrastructures.

Hello team, I'm excited about the opportunity to contribute to LitmusChaos for Hacktoberfest and I would like to work on this issue.

I have read the issue description and I understand that an "Overview" section needs to be added at the beginning of the ChaosCenter Developer Guide.

Here's how I plan to approach this:

1. I will locate and open the file. website/docs/developer-guide/chaoscenter-developer-guide.md

2. At the top of the document, I will add the "Overview" section.

3. I will copy the provided content for the overview into this new section.

4. I will ensure that the formatting of the new section is consistent with the rest of the document.

5. Once the changes are made, I will open a pull request for revien.

Please assign this issue to me. Thank you
