fix: pin jsoup to 1.23.1 to resolve XSS vulnerability

jsoup 1.22.x is pulled in transitively via com.contentstack.sdk:utils
and is flagged by Snyk for a Cross-site Scripting (XSS) issue, fixed
in 1.23.1. Pin the version in dependencyManagement following the
existing pattern used for other contentstack-utils transitive deps.
