Update kotlin-spring-additionalproperties samples
* fix(kotlin-spring): add missing constructor parentheses for hashmap models
This commit fixes a bug in the kotlin-spring generator where models
defined with additionalProperties would result in uncompilable code.
The generated data class was missing the constructor invocation '()'
when inheriting from a map type.
This has been corrected to only add parentheses when the parent is a map.
The existing samples have been regenerated to reflect this change.
* Trigger CI
