Update Gradle Wrapper to 8.2.1 for Enhanced JDK20 Compatibility

- **Reason for Upgrade**: The migration to JDK20 ([reference](https://github.com/opensearch-project/opensearch-build/blob/aa65a8ecd69f77c3d3104043dd1c48dff708bffa/manifests/3.0.0/opensearch-3.0.0.yml#L9)) rendered the current Gradle version (7.6.1) incompatible. - **Actions Taken**: - **Gradle Wrapper Update**: Upgraded the Gradle wrapper to version 8.2.1 to maintain compatibility with JDK20. The gradle wrapper files are generated using the `./gradlew wrapper` command. - Applied `spotless` due to new formatting requirements in Gradle 8. - Resolved test "jar hell" issues. Gradle 8 introduced internal JARs to the test classpath that conflicted with dependencies from `org.junit.vintage:junit-vintage-engine`. As a remedy, these conflicting JARs have been excluded. - **Relevant Pull Requests**: - [Alerting#893](https://github.com/opensearch-project/alerting/pull/893/files) - [ML-Commons#892](opensearch-project/ml-commons#892) - [Security PR](opensearch-project/security#2978) - **Verification**: Successfully verified the changes using `gradle build`.
