[REQ][JAVA]: Add @com.fasterxml.jackson.annotation.JsonProperty when @lombok.Data is used

Description

When using @lombok.Data in additionalModelTypeAnnotations, the getters for fields are not generated. While @com.fasterxml.jackson.annotation.JsonProperty is only placed on getter methods, this causes a problem when the property name is in kebab-case rather than the default camel-case.

openapi-generator version

7.6.0

OpenAPI declaration file content or URL

pojo.mustache

Command line used for generation

Regular maven build.

Steps to reproduce

Configuring the maven plugin using the following configOptions:

<configOptions>
    <library>spring-cloud</library>
    <useSpringBoot3>true</useSpringBoot3>
    <useResponseEntity>false</useResponseEntity>
    <bigDeciamlAsString>true</bigDeciamlAsString>
    <dateLibrary>java8-localdatetime</dateLibrary>
    <useEnumCaseInsensitive>true</useEnumCaseInsensitive>
    <configPackage>com.kbakhtiari</configPackage>
    <generatedConstructorWithRequiredArgs>false</generatedConstructorWithRequiredArgs>
    <additionalModelTypeAnnotations>
        @lombok.Data
        @lombok.NoArgsConstructor
        @lombok.AllArgsConstructor
        @lombok.Builder(toBuilder = true)    
    </additionalModelTypeAnnotations>
</configOptions>

Adding the following code snippet to pojo.mustache:

{{#lombok.Data}}
@JsonProperty("{{baseName}}")
{{/lombok.Data}}

Start with modules/openapi-generator/src/main/resources/JavaSpring/pojo.mustache and review how additionalModelTypeAnnotations and @lombok.Data affect generated model properties. Reproduce the kebab-case property scenario with the stated Maven configuration, then verify that generated Java models include the needed JsonProperty annotation and preserve the existing Lombok annotations.
