Dask 2026.1.2 breaks ome-zarr-py support

[LucaMarconato]

The latest dask changes some parameter names and is not supported by ome-zarr-py. Since we depend on ome-zarr-py, we need to put an upper bound on dask until this is addressed.

Could this be loosened again with ome_zarr v0.16 supporting dask v2026.3.0 via ome/ome-zarr-py#534 ?
