Improve Code of Conduct visuals

[Zunairah-k]

Issue Description

The Code of Conduct is currently text-heavy. We can make it more engaging by adding banners, dividers, and small GIFs/icons to highlight important sections. This will make it easier to read and give it a welcoming vibe for new contributors.
