The code generation produces links that are relative to the root of the `semantic-conventions` repo and therefore do not resolve. [example here](https://github.com/open-telemetry/semantic-conventions-java/blob/b3f3d0267414c5ee9a37843aa60cc186039b7296/src/main/java/io/opentelemetry/semconv/resource/attributes/ResourceAttributes.java#L49). We should fix the code gen so that links resolve.
