Google Classroom Dark Theme
The old code had a lot of unneccesary stuff, was old, and broke with a UI update,
so I rewrote the entire theme from scratch. This version has more customizations.

Since there was no good dark theme for Google Classroom and the Dark Reader extension
didn't work perfectly, I decided to create my own dark theme for Google Classroom.

2.3.0.0 (2025-1-7):
- Fix white popups
- Add dark theme for file uploading from Google Drive
