Update pandas to 2.1.1 and duckdb to 0.9.0
Update `pandas` dependency to 2.1.1 version, their latest patch release: https://github.com/pandas-dev/pandas/releases/tag/v2.1.1

Note that:
- several pandas versions were installed
- most of them were 2.0.2: there was a newer 2.0.3 patch release
- one was 2.1.0: for this, the newer 2.1.1 patch release is recommended

Additionally, update `duckdb` dependency to 0.9.0: https://github.com/duckdb/duckdb/releases/tag/v0.9.0
Note there was an incompatibility with `pandas=2.1.1` for `duckdb<0.9.0`. See comment below: https://github.com/huggingface/datasets-server/pull/1827#issuecomment-1729090034
