Reduce payload size for repository files

[AjayvirS]

Describe the bug

When comparing the template with the solution submission, also binary files like .jar are included in the request unnecessarily increasing the payload size. This has been patched for one call in the following issue: #9929.

This filter should be extended to other calls, e.g. when sending data to Pyris, we should not include binary files. Other rest calls where the binary files are not required (i.e. in diff viewers) a filter should be added to omit these files.

To Reproduce

n/a

Expected behavior

Payload size should be reduced where binary files are not needed
