Review Comment:
I didn't find an authoritive document explicily saying it's not supported
from pyarrow. But I tested it locally and it doesn't work for Alibaba. Kevin
also helped to check the pyarrow code in [this
comment](https://github.com/apache/iceberg-python/pull/1453#discussion_r1902287419).
Seems pyarrow is using the `x-amz-bucket-region` header to determine the
bucket region, which seems to be an AWS thing.
