Test resources are ignored during "nativeTest"

[meletis]

The test resources are not included at runtime when executing "nativeTest".

Steps to reproduce the behavior:

1. Checkout the following repository at the specific branch: https://github.com/meletis/native-build-tools-bug-report/tree/native-test-failure
2. Execute the following command and make sure all tests are okay:

$ ./gradlew test

4. Then execute the following command, which will fail as shown in the logs:

$ ./gradlew nativeTest

Expected behavior:

The tests should finish successfully, just like the ./gradlew test does. Instead, the following error appears in the logs:

Resource with path db/mysql_conf_override could not be found on any of these classloaders: [jdk.internal.loader.ClassLoaders$AppClassLoader@2f7c7260]

Security report:
 - Binary includes Java deserialization.
 - Use '--enable-sbom' to embed a Software Bill of Materials (SBOM) in the binary.
------------------------------------------------------------------------------------------------------------------------
Recommendations:
 PGO:  Use Profile-Guided Optimizations ('--pgo') for improved throughput.
 INIT: Adopt '--strict-image-heap' to prepare for the next GraalVM release.
 HEAP: Set max heap for improved and more predictable memory usage.
 CPU:  Enable more CPU features with '-march=native' for improved performance.
 QBM:  Use the quick build mode ('-Ob') to speed up builds during development.
