Bump the oldest pyarrow version to 14.0.2 in test matrix (#17611)

A recent nightly failure discovered by @davidwendt here: https://github.com/rapidsai/cudf/actions/runs/12367794950/job/34543121050 indicates an environment cannot be created with `pytorch>=2.4.0` and `pyarrow==14.0.0 & 14.0.1`. Thus this bump to `14.0.2`.
