Every Year

Update academic year and semester in website/src/config/app-config.json, and add current academic year to archive years
In app-config.json, update examAvailability to include only the semesters where exam information is available
Update with next year's holiday data from https://github.com/rjchow/singapore_public_holidays and delete old data, then run scripts/holidays-csv-to-json.js
Update website/src/data/academic-calendar.json with data for the new academic year
Add announcement to website
Update academic year in scrapers/nus-v2/src/config.ts
