Migrate Jackson2ObjectMapperBuilderCustomizer to JsonMapperBuilderCustomizer

Proprietary

Changes Jackson2ObjectMapperBuilderCustomizer to Spring Boot 4's JsonMapperBuilderCustomizer, whose lambdas receive a JsonMapper.Builder instead of a Jackson2ObjectMapperBuilder. Builder calls in such a lambda that have a JsonMapper.Builder counterpart are renamed, such as modulesToInstall to addModules.
