Update contributing.md

[AvineshTripathi]

Is your feature request related to a problem? Please describe.
The current contributing.md has not been touched for a long time and needs to be revisited to help new contributors get familiar with the project.

Describe the solution you'd like

• We should add more detailed explaination to how the project is structured and how can an - individual run everything locally and contribute.
• We should also write about testing things and how we can help folks with necessary env to test their code
• We also want to tell folks how they can contribute without any code(maybe talk about initiatives we have started)
• Maybe a roadmap?
