IDEA: Remove cookiecutter files if code.json already exists

[natalialuzuriaga]

If a code.json already exists in the repository, the codejson directory containing cookiecutter files is not needed and can be removed from the repository. Maybe this can be removed in the generated PR

This kinda feels like feature creep since the cookiecutter files dont have to do with creating or maintaining code.json. This could potentially be moved to a github action that lives in this workflow
