Disable appending `def` to generated class names after upgrading from 5.30 -> 7.6.0

[drewjocham]

Description

After upgrading the openapi-generator-maven-plugin from version 5.3.0 to 7.6.0 def is appended to all the generated class names. Example Action.java is now Actiondef.java. The only thing that has changed is the version. How can we stop this from happening?

can you please share the spec?

don't think we add the def suffix to the model name behind the scene

@wing328 Thanks for responding. Are you referring to a xxx.api.json file or xxx.def.json file?

bump. There was a change between 5.4.x and 6.1.x. After 6.1.x def is appended to all my entities.
