Transformation not supported error with OpenAPI 3.1 file

[fokopratik]

We're using the Quarkus OpenApi Generator extension. If we set version to 3.1.0 getInfoFromApiDoc method still calls transformDocument which doesn't have code to handle version 3.1 and ends up throwing the following error

java.lang.RuntimeException: Transformation not supported.
