Add CODE_OF_CONDUCT.md

[Techy-ninja]

Hi maintainers! 👋
I'd love to add a CODE_OF_CONDUCT.md to help make this project more welcoming and safe for all contributors. It’s a small doc that sets expectations of Do's and Dont's. I can open a PR with this ready to go.
Would you like me to go ahead?

There is already a PR, which I believe we will not accept as we would have a CoC managed on the org level
