Making CONTRIBUTING.md file for the orcahome

[aayushsrivastava9760]

Currently, there's no file explaining how to contribute and set up the website locally with all the commands and steps in a systematic order. It would be better if the CONTRIBUTING.md file is added explaining how to set up the website locally, report bugs, Provide feedback or Request features, etc.

That would be great if we could have this made so that people can contribute easily! @aayushsrivastava9760

@hgordon6634 @paulcretu I'd like to start my contributions to orcahome from this issue. So, you can assign it to me if its urgent.

Closing this issue because I will be handling it as part of #22. For dev setup instructions, the current README (generated by default with create-next-app) works fine
