Use spotless / palantirJavaFormat - 2.56.0 for all JDKs

Spotless start using palantir-java-format 2.57.0 on Java 21 - on older jdks different versions are used.

It causes a different code format depends on using JDK

references:
 - diffplug/spotless#2447
 - diffplug/spotless#2503
 - palantir/palantir-java-format#1320

As issue - diffplug/spotless#2503 was closed, reverting spotless plugin to an older version is not a resolution.
