You example fails with both grpc 1.57 & 1.58 in the following way (added
linebreaks to `FlightUnavailableError` message for legibility)
```
Starting server...
Flight server listening on grpc://0.0.0.0:8815
Running client...
Traceback (most recent call last):
File "test_arrowflight.py", line 19, in <module>
