Adding setup script for dev environment

[alsoto25]

Description

Adding a small setup script to run the first time a contributor clones the repository. This allows all contributors to freely make changes in the /dev directory without the changes appearing staged. By doing this, we can keep the dev/ directory as clean as possible and avoid accidentally committing changes that are only relevant for a specific test or for a specific use case.
