openapi-java deployment module fails to compile due to missing DefinitionReader class

[jamesnetherton]

io.smallrye.openapi.runtime.io.definition.DefinitionReader is removed in SmallRye OpenAPI 3.12, which breaks the build time logic in the openapi-java extension here:

https://github.com/apache/camel-quarkus/blob/main/extensions/openapi-java/deployment/src/main/java/org/apache/camel/quarkus/component/openapi/java/deployment/OpenApiJavaProcessor.java#L242-L244

The only fix I found is to use OpenApiParser.

https://github.com/apache/camel-quarkus/blob/quarkus-main/extensions/openapi-java/deployment/src/main/java/org/apache/camel/quarkus/component/openapi/java/deployment/OpenApiJavaProcessor.java#L232-L237

But, that class is marked as deprecated and has a comment stating that it may be removed or have reduced visibility in the future. So we probably need to find an alternate solution.

Well, I can take a look. IIRC these codes were borrowed from quarkus somewhere before.

It could be alter to use OpenAPIDefinitionIO

Done in #6523.
