Refactor non-active repository link template

The non-active repository link template in the course page repository dropdown has been refactored. Changes include:

 • Added proper indentation and line breaks for better readability.
 • Reorganized the image tags for the repository language logos.
 • Added a missing newline at the end of the file.

These changes improve the structure and maintainability of the template.
