chore(openchallenges): upgrade the OC image service to Gradle v8.4

[tschaffter]

Closes #2335

Changelog

• Update Gradle for the image service
• Update the dependencies of the image service to remove deprecation warnings

Notes

• I did not upgrade any Spring packages because this ended up breaking the service. I will keep this upgrade as future work. Also, I should ideally continue to keep the version of the Spring packages aligned across all Spring services.

Error with the Discovery client

The image service no longer works after updating the dependencies. The images do not appear in the OC app.

EDIT: The service returns responses successfully once reverting to the previous version of Spring packages. The above error still occurs but it does not appear to be linked to the service not returning successful responses.
