fix(kotlin-spring): add jackson-annotations dependency for Jackson 3

Spring Boot 4's BOM does not manage tools.jackson.core:jackson-annotations
transitively, causing unresolved reference errors at compile time when
model imports use the tools.jackson.annotation package.

Adds the explicit dependency to all three library templates (spring-boot,
spring-cloud, spring-declarative-http-interface) for both Gradle and Maven.
