Add Style Checking for React in CI/CD Pipeline

[jacob-macleod]

For python, pylint is run in the pipeline to make sure the code adheres to PEP8 standards. If it does not, black can be run manually to make it conform by formatting the files. Your task is to:

• Find equivalent tools for the React code
• Implement the equivalent of Pylint but for React in the pipeline
• Find a formatter (like black, but for React, following React standards), and manually run it on the React code in the frontend folder
