Code Refactoring:

• removed import React from 'react'; from files in accordance with React 17

• fixed hydration errors by changing <p> to <div>
• created testimonial-class to ensure cascading styling
• added dimensions to images in gm.js to ensure correct rendering
• replaced @import with @use in .scss files for compatibility with latest sass version

Testing

The deploy preview for the website loads each page correctly, with all components rendering as expected. No issues with hydration errors or broken styling.

Possible Changes

• update eslint and eslint-config-next to their latest versions (this is a breaking change and will require several modifications to current configuration for it to work properly)
• update react and react-dom to their latest versions once react-accessible-accordion supports them
• update to using node 22.13.1
• fix image rendering for carousel

Checklist

• Code follows the project's style guidelines.
• Documentation has been updated where necessary.
• All checks pass and deploy builds with no errors.

lgtm, everything seems to render properly (besides the images in the carousel, not impacted by this PR) and no errors within the DevTools menu
