Review "UserWarning: Pydantic serializer warnings: Expected int but got int64" in cellvoyager-to-ome-zarr init task

[tcompa]

When running example01 of fractal-demos within fractal-containers, I observe the warning at the end of 0_convert_cellvoyager_to_ome_zarr/0.log:

I could not quickly identify the relevant int field. My first guess (unverified) is that this concerns bit_depth (which comes from a pandas DataFrame), and then affects channel.window.max (which is expected to be an int, in the Window model).
