Fixed Gradle script for dependency downloading (joernio#4567)

`configurations.default` can not be resolved by default.
The previous hack with `.setCanBeResolved(true)` will be deprecated with Gradle 9 and finally removed / disabled in future releases (same for `implementation`). The proper way to do this is by re-using a resolvable configuration (resolvable by default) in the `from` clause of the task.

More info: https://docs.gradle.org/current/userguide/declaring_dependencies.html#sec:resolvable-consumable-configs and https://docs.gradle.org/current/userguide/java_library_plugin.html#sec:java_library_configurations_graph
