arrow 57.1.0 ? Or should we wait a bit to let arrow-rs bake a bit more?

In theory, we shouldn't have to do anything to DataFusion 51.0.0 to be able to use arrow 57.1.0 as it is semver compatible (and @etseidl and I are madly testing to make sure this is true):

• Release arrow-rs / parquet Minor version 57.1.0 (November 2025) arrow-rs#8464

I do think several tests will need to be updated to get them to pass with arrow 57.1.0 (see #18820) but I am not sure if we should do that or not
