Python(fix): update dependencies

[alexluck-sift]

Addresses missing pyarrow dependency and an error with protobuf.

Versions of protobuf >= v5 no longer produce the following error:

.../site-packages/sift_client/_internal/low_level_wrappers/data.py", line 104, in _get_data_impl
    request = GetDataRequest(**request_kwargs)
TypeError: Message must be initialized with a dict: sift.data.v2.GetDataRequest
