FE Implement chatgptQuestions in JobApplicationInterviewQuestions

[aloraalee]

Currently the JobApplicationInterviewQuestions component is using dummy questions.

• Switch the dummy questions for the chatgptQuestions returned in the useEffect
• Refactor the fetch request to move it to trackerApiCalls.tsx
• Remember to import to JobApplicationInterviewQuestions
• Update mockInterviewQuestions.json with the correct format from the backend data by using postman on the Create interview_questions endpoint
• Write / Update Cypress tests to reflect the fetch call including sad paths, edge cases and throwing errors.
• Make sure the tailwind.css matches the updates to the README
• Create the styling for the loading page to match the wireframe

This connects to task #138
