MIP task leads to missing .zgroup file on the row level #780

Originally reported by @enricotagliavini

It looks like the MIP Zarr plates generated by our MIP task miss the .zgroup Zarr files on the row level.

myplate.zarr/B/.zgroup exists, but myplate_mip.zarr/B/.zgroup appears to be missing

Let's fix this, as it can interfere with the API reading the Zarr plates, if it checks for the zarr version.

The only thing that's typically in this .zgroup file is:

{
    "zarr_format": 2
}
