[BekahHW]

Description

The project is currently using Prettier v2.2.1 which is outdated. We should upgrade to the latest version to get bug fixes, performance improvements, and new features.

Tasks

• Update Prettier version in package.json from "^2.2.1" to latest version
• Update package-lock.json/pnpm-lock.yaml accordingly
• Test that formatting still works correctly with npm run format and npm run check
• Fix any formatting changes that result from the upgrade
• Update any Prettier configuration if needed

Acceptance Criteria

• Prettier is updated to latest stable version
• All existing formatting commands work correctly
• No formatting regressions introduced
• Documentation builds successfully

This is a great issue for new contributors to get familiar with the project's build process!
