Adds an opt-in override to spring-security-dependencies so it can be
built against a specific Spring LDAP version instead of whatever's
declared in the version catalog, matching the existing pattern for
Spring Framework/Reactor/Spring Data/Micrometer. Passing
-PisOverrideVersionCatalog=true -PspringLdapVersion=X takes precedence
over the catalog. Default behavior (no properties passed) is unchanged.
