[META] Set OpenSearch 3.0.0 baseline JDK version to JDK-21

[reta]

Please describe the end goal of this project

Currently, the 3.0.0 baseline JDK version is set to JDK-11. The Apache Lucene 10 is going to require JDK-21 and it would make sense to align the OpenSearch JDK baseline requirements with that.

In order to make the migration as painless as possible, the suggestion is to start from dependent components (plugins, clients, extensions, libraries) and finish up with core, for the following reasons:

• if we change core to JDK-21 baseline (bytecode), it will break all and every dependent component
• however, because we always build core with JDK-21 (and bundle it in as well with JDK-21), there won't be any issues dealing the dependent components that are on JDK-21 baseline
