Update README with poetry setup and contributing guidelines

PR Type (Documentation)

Short Description

This PR updates the README to clarify the setup process for Poetry and provide clearer contribution guidelines. It simplifies the environment setup instructions by using poetry install instead of python3 -m poetry install which causes errors. Now cyclops should be reproducible. Additional instructions for testing dependencies and building API documentation with Sphinx have also been clarified.
