Update Gradle version and support for Java 17

Updated the gradle version from 8.4 to 8.5 in gradle-wrapper.properties. Also, added explicit support for Java 17 in build.gradle file, which renders the application compatible with the latest Java version. Additionally, removed 'jacoco' - reliance on this plugin can be eliminated for our use case at present.
