Adding CodeOfConduct.md file

[AnushkaChanda]

I suggest adding a Code of Conduct file to the project repository.

A Code of Conduct helps in:

1.Defining standards for how to engage in a respectful and inclusive way.
2.Setting clear expectations for behavior from all contributors.
3.Making the community more welcoming and professional.

This will help establish a healthy and collaborative environment as the project grows.

Please add label and assign this issue to me.
