Programming Exercise: Template and solution repository comparison contains unnecessary binary files

[maximiliansoelch]

Describe the bug

When comparing the template with the solution submission, also binary files like .jar are included in the request unnecessarily increasing the request size.

To Reproduce

1. Go to a programming exercise edit page
2. Open your browser's dev tools
3. Click on 'Review Changes' in the Template/Solution Comparison section
4. Look at the network requests and see that binary files like .jar files are included in the request

Expected behavior

Common binary files like .jar, .exe, etc. should be excluded from these REST requests to decrease the request size.
