Suppress Hibernate Validator logging

With every invocation of Pantools I'm getting the following log message from the Hibernate Validator (example):

$ java -jar target/pantools-3.4.jar build_pangenome ...
Aug 25, 2022 12:31:52 PM org.hibernate.validator.internal.util.Version <clinit>
INFO: HV000001: Hibernate Validator null

This output needs to be suppressed.
