OAPI: remove '-dirty' suffix from the version number in generated code

The version number used in the OpenAPI-generated code shouldn't contain
the `-dirty` suffix. In the common development workflow, those files
will always be dirty; because they're only committed after things are
locally working, the implementation has already been written.
