Refresh CODEOWNERS (#2823)

# Pull Request

## 🤨 Rationale

- Simplified so only changes from the default CODEOWNERS are defined
- Updated so each entry had two active CODEOWNERS, thanks @mollykreis
for signing up for Angular 🎉

## 👩‍💻 Implementation

See above.

## 🧪 Testing

On the files view GitHub reports the CODEOWNERS file as valid

## ✅ Checklist

- [x] I have updated the project documentation to reflect my changes or
determined no changes are needed.
