hashCode() should not be called on array instances

Recipe IDorg.openrewrite.staticanalysis.RemoveHashCodeCallsFromArrayInstances
Artifactorg.openrewrite.recipe:rewrite-static-analysis

Replace hashCode() calls on arrays with Arrays.hashCode() because the results from hashCode() are not helpful. Arrays inherit hashCode() from Object, which returns an identity-based value unrelated to the array contents, so two arrays with identical elements will produce different hash codes.
