Description

Starting with Lucene 9.7.0, the vector search module uses the incubating Java Panama Vector API if a user is running Java 20 or 21.

Unlike the Panama Memory optimizations, the Panama Vector optimizations require a command line option to java, because the APIs are further away from stability. This command line option is: "--add-modules jdk.incubator.vector". We should set this flag by default for users running Java 20 and 21
