[Bug]: Fix OSB's Integration tests

[OVI3D0]

Describe the bug

Recently, OpenSearch was updated to Lucene 10, which included updating the minimum JDK version to 21 for gradle operations instead of JDK 11. This began causing failures in OSB's integration tests since we use JDK 17:

osbenchmark.exceptions.BuildError: Executing './gradlew clean' failed. The last 20 lines in the build log file are:
=========================================================================================================
	* What went wrong:
	A problem occurred evaluating project ':buildSrc'.
	> At least Java 21 is required to build opensearch gradle tools

This solution was introduced temporarily to swap between JDK versions when needed and run the integration tests, but this is only a fix for integration tests run using Github Actions, and does not help if users want to run their tests locally using make it.

Another solution proposed was to add JDK 21 to the provision_config resources in OSB, but this caused different failures referenced here:

https://github.com/opensearch-project/opensearch-benchmark/actions/runs/13001769222/job/36261656956#step:11:243
https://github.com/opensearch-project/opensearch-benchmark/actions/runs/12999003364/job/36253370447#step:9:145

More investigation is needed to figure out what the best solution is going forward.

To reproduce

Run integration tests using GH actions

Expected behavior

Integration tests run normally without JDK failures.

Relevant log output

When attempting to use JDK 21 for gradle operations and JDK 17 for opensearch operations:

Error:  Cannot execute-test. JAVA_HOME points to JDK 17 but it should point to JDK 21.
