Add CONTRIBUTING.md file to repository

[thevijayshankersharma]

Currently, the repository lacks a CONTRIBUTING.md file, which serves as a crucial guide for potential contributors on how to effectively participate in the project. The absence of this file makes it challenging for new contributors to understand the project's contribution guidelines, coding standards, and other important information.
