The testbom defines a FasterXML version; current 2.13.4. Try the 2.14.3 currently used in full WF; if that blows up go to 2.13.5.

https://mvnrepository.com/artifact/com.fasterxml.jackson.core/jackson-databind/2.13.4.1 reports a CVE against the one we currently use, although the CPE for that CVE disagrees. But anyway, might as well bump it. Dependabot kind of tried with https://github.com/wildfly/wildfly-core/pull/5620/files
