CI: temporary skip parquet tz test for pyarrow>=2.0.0
See https://github.com/pandas-dev/pandas/issues/37286, this PR is not the actual fix, but at least ensures we don't have failing CI in other PRs (I prefer to skip the test instead of pinning pyarrow to <= 1.0, since all other tests are passing on 2.0, which is good to still run)
