[REQ] Feature Request Description Can we not generate empty package org.openapitools.configuration?

Is your feature request related to a problem? Please describe.

When I generate SpringBoot3 WebFlux backend code. config like this below. I noticed that it generate an empty package org.openapitools.configuration, I was wondering if we can remove this empty package.

                      <execution>
                        <id>thing</id>
                        <goals>
                            <goal>generate</goal>
                        </goals>
                        <configuration>
                            <generatorName>spring</generatorName>
                            <apiPackage>com.huaweicloud.iiot.thingmanager.api.thing</apiPackage>
                            <invokerPackage>com.huaweicloud.iiot.thingmanager.invoker.thing</invokerPackage>
                            <modelPackage>com.huaweicloud.iiot.thingmanager.model.thing</modelPackage>
                            <inputSpec>${project.basedir}/src/main/resources/yaml/thing.yaml</inputSpec>
                            <generateApis>true</generateApis>
                            <generateModels>true</generateModels>
                            <generateSupportingFiles>true</generateSupportingFiles>
                            <skipValidateSpec>true</skipValidateSpec>
                            <supportingFilesToGenerate>ApiUtil.java</supportingFilesToGenerate>
                            <configOptions>
                                <delegatePattern>true</delegatePattern>
                                <library>spring-boot</library>
                                <openApiNullable>false</openApiNullable>
                                <reactive>true</reactive>
                                <useSpringBoot3>true</useSpringBoot3>
                            </configOptions>
                        </configuration>
                    </execution>

Describe the solution you'd like

If org.openapitools.configuration is empty, don't generate it.

Additional context

If community needs volunteer, I'm willing to help submit a PR. But I need some hints :)

Start by reproducing the SpringBoot3 WebFlux generation with the Maven configuration shown, especially generateSupportingFiles and supportingFilesToGenerate. Trace the Spring generator's package and supporting-file generation, then add coverage for this configuration; done means org.openapitools.configuration is absent when it would otherwise be empty.
