Run JDK 21 workflows with latest JDK (21.0.7 as of April 2025)

[abhishekrb19]

JDK 21.0.6 was released in April 2025. This change is prompted by a recent dev discussion.
It’s effectively another attempt at #17694, which was reverted in #17806 due to sporadic segfaults observed with JDK 21.0.6.

Hopefully the segfaults don't occur with the latest JDK and fixes #17429.

This PR has:

• been self-reviewed.
  • using the concurrency checklist (Remove this item if the PR doesn't have any relation to concurrency.)
• added documentation for new or modified features or behaviors.
• a release note entry in the PR description.
• added Javadocs for most classes and all non-trivial methods. Linked related entities via Javadoc links.
• added or updated version, license, or notice information in licenses.yaml
• added comments explaining the "why" and the intent of the code wherever would not be obvious for an unfamiliar reader.
• added unit tests or modified existing tests to cover new code paths, ensuring the threshold for code coverage is met.
• added integration tests.
• been tested in a test Druid cluster.

let's run the all jdk tests a few times :)

Hmm, one of the indexing module UTs org.apache.druid.indexing.common.task.IndexTaskTest crashed with a segfault with JDK 21 (21.0.7):

Closing this as the latest JDK 21.0.7 still appears to have segfaults.
