Suggest a fix/enhancement

allOf is generating the file with Dto and using in extends with same name with dto, only oneof has the issue, it can be handle similar to allOf

Reproduce the generated Java models from the supplied Node, EventNode, SwitchNode, and ActionNode schema using the Maven plugin configuration with modelNameSuffix set to dto. Compare the oneOf-generated interface reference with the allOf behavior; done means the generated ActionNodeDto references the suffixed OneOfNodeDto name and the Java output compiles.
