Unpin DuckDB when upstream releases fix for regression

[danielballan]

DuckDB issued a release last night, which is likely the cause of the wall of these errors on last night's scheduled CI run.

FAILED tiled/_tests/test_writing.py::test_append_partition[orig_file2-file_to_append2-expected_file2] - ModuleNotFoundError: No module named 'adbc_driver_duckdb'

[danielballan]

Confirmed with a simple example that this is a regression in DuckDB. Reported upstream.

Upstream fix: duckdb/duckdb-python#81

Just waiting for a release now.

FYI: we released v1.4.1 last week, adbc_driver_duckdb should be back.

Thanks @evertlammerts! It was generous of you to follow up here. Appreciated.
