3.x: Fix CI to run tests

Currently CI for `scylla-.3.x` is not running any tests.
It [returns](https://github.com/scylladb/java-driver/actions/runs/10582193524/job/29321305230) the following on every test suit:
```
Tests run: 0, Failures: 0, Errors: 0, Skipped: 0
```

We need to fix maven to start picking up tests.
