Add a CODE_OF_CONDUCT.md file

[whyvineet]

Currently, the project lacks a CODE_OF_CONDUCT.md file. A Code of Conduct is important to outline the expected behavior for contributors and ensure a welcoming environment for everyone involved. It helps to address any issues that arise from misconduct and sets clear guidelines on how to report such behaviour.

Task:

• Create a CODE_OF_CONDUCT.md file in the root directory of the project.
• Include a clear set of guidelines for expected behaviour.
• Provide steps for reporting violations.
• Consider using a well-known template like the Contributor Covenant Code of Conduct.
