Description

Currently the Iceberg time and date partition transforms are wrong if the data is before the epoch.

There's already an Iceberg pull request about it: https://github.com/apache/iceberg/pull/1981

Becauce of this bug Impala doesn't prune Iceberg partitions if the predicate refers to timestamps before the epoch.

Once the above pull request is merged we need to update our Iceberg dependency.
