chore: updating codeowners to remove mobile-devs from component libra…

…ry (#11709)

## **Description**

This PR updates the `CODEOWNERS` file by removing mobile developers from
the `component-library` folder. The goal is to:

- **Prevent Prop Bloat**: Streamline components and avoid unnecessary
complexity.
- **Maintain Consistency**: Ensure that we achieve 1:1 consistency
across Figma, Extension, and Mobile environments.
- **Reduce Tech Debt**: Centralize control over merge permissions to
avoid inconsistencies and maintain clean component architecture.

## **Related Issues**

Fixes: N/A

## **Manual Testing Steps**

1. Review the changes made to the `CODEOWNERS` file.
2. Verify that mobile developers no longer have ownership permissions
over the `component-library` folder.
3. Confirm that merge permissions reflect the correct teams for
maintaining the design system and consistency.
