Description

In the current version I have seen following behaviour. If I´m setting <swaggerDocketConfig>false</swaggerDocketConfig> to false, the class OpenAPIDocumentationConfig.java with Docket (springfox) is still generated.

For me it looks like there are some impacts to other properties.

Expected behaviour

Don´t generate OpenAPIDocumentationConfig.java if property is set to false.

config-snipped from pom.xml:

<configuration>
	<inputSpec>src/main/resources/schema/my.yaml</inputSpec>
	<generatorName>spring</generatorName>
	<library>spring-boot</library>
	<configOptions>
		<delegatePattern>true</delegatePattern>
		<swaggerDocketConfig>false</swaggerDocketConfig>
	</configOptions>
</configuration>

openapi-generator version

5.2.1

Start by locating OpenAPIDocumentationConfig.java and the code that reads the swaggerDocketConfig option for the spring generator. Reproduce the issue with the pom.xml configuration shown, using swaggerDocketConfig=false. Done means OpenAPIDocumentationConfig.java is not generated while the other configuration options continue to work.
