airbyte fails to load after airbyte-protocol was updade to 0.14.4

`import airbyte` throws the following error since a few hours ago, when 0.14.4 was released.
It is working fine with 0.14.3!

```
NameError: name 'StreamDescriptor' is not defined

Stacktrace:
File /local_disk0/.ephemeral_nfs/cluster_libraries/python/lib/python3.11/site-packages/airbyte_cdk/models/airbyte_protocol.py:58, in AirbyteStreamState()

57 class AirbyteStreamState:
---> 58 stream_descriptor: StreamDescriptor # type: ignore [name-defined]
59 stream_state: Optional[AirbyteStateBlob] = None
```

tested with:
- airbyte==0.23.0
