Subject: [PATCH 4/5] Fix: Remove invalid cache-configuration parameter from
 GitHub Actions

The cache-configuration parameter doesn't exist in gradle/actions/setup-gradle.
Configuration cache is controlled by gradle.properties setting only.
This fixes the build failure caused by the invalid parameter.

Subject: [PATCH 5/5] Revert: Remove org.gradle.configuration-cache=true due to
 build failures

The configuration cache feature is causing build failures in CI.
Reverting gradle.properties to the state before configuration cache was enabled.
This removes the org.gradle.configuration-cache=true setting.
