Description

As indicated in IGNITE-17658, --add-opens=java.base/java.lang.invoke=ALL-UNNAMED is required to serialize lambdas.

However this flag is not included in the Java 17 section of the Ignite Java Quick Start guide: https://ignite.apache.org/docs/latest/quick-start/java 

Please add this so that Ignite users that require serialization of lambdas (such as scan query filters and entry processors) don't run into this problem:
