Simplify codeowners file (#7069)

# Pull Request

## 📖 Description

The CODEOWNERS file is too complex and we have a limited number of reviewers at present so this change should help move things through the development process more swiftly while maintaining quality for trusted reviewers.

This change also removes @nicholasrice due to current write permissions not being available for the user which throws an error in GitHub.
