chore: remove unnecessary upstreamed JCS logging configuration

dependency-check/DependencyCheck#8117 upstreams this configuration to dependency-check-core, so this is no longer necessary. It wasn't always working correctly/deterministically for some reason (possibly Gradle's internal use of slf4j?), so hopefully this addresses the situation more reliably for the Gradle plugin.
