New Recipe Checklist

• [ x ] My PR is in the format of Add <project-name> recipe
• [ x ] My recipe is reproducible and explains everything needed to run successfully. If my code has external dependencies, I make mention of them.
• [ x ] My code is easily understandable and/or well-commented.
• [ x ] If my recipe requires a new category (e.g. creating a monitoring/ folder in devops/), I have encapsulated my project within its own subfolder so that others can add their own recipes as well.
• [ x ] If my recipe uses Prefect < 2.0, my code is within the prefect-v1-legacy/ folder.
