Developers: Update documentation with Intro and Demos

[k-farruh]

This commit introduces several updates to the documentation page to enhance clarity and provide users with practical examples of how to use our project:

• Introduction Section Added: A comprehensive introductory section has been crafted to give new users an overview of the project, its purpose, and its value proposition. This serves as a starting point for anyone looking to understand what the project is about.
• Demo Examples: To demonstrate the project's capabilities in real-world scenarios, two demo examples have been included. These demos are designed to showcase how the project can be implemented and to provide users with a hands-on experience straight from the documentation.

It's important to note that, currently, there is no dedicated "Developers" section in our documentation. We recognize the significance of having a section that addresses the concerns and needs of developers who are contributing to or interested in the project. However, this will be considered for future updates to ensure our documentation is comprehensive and caters to all our users, including developers.

For now, developers looking to contribute can still find relevant information through the existing sections of the documentation, and they are encouraged to review the contribution guidelines for detailed instructions on how to get involved with the project.
