spring-injection:InjectablesMustNotBeInstantiated false-positive when using helper methods

[janmaterne]

When a @bean method in configuration class uses a helper method to create the injectable, that helper method is marked as invalid.

@Configuration
public class MyConfig {

    @Bean RestTemplate myService() {
        return createRestTemplate("http://baseurl");
    }

    // this is marked as error with "jQAssistant Spring Plugin <unknown version> [jqa.plugin.spring]", should be 2.1.0
    private RestTemplate createRestTemplate(String baseurl) {
        var template = new RestTemplate();
        // standard configuration + baseurl
        return template;
    }
}
