Deps missing from B-F update site

see: https://forum.image.sc/t/ome-zarr-file-size-compared-to-czi/84932/18

```
def uri = "https://uk1s3.embassy.ebi.ac.uk/idr/zarr/v0.1/9836832.zarr"
def reader = new loci.formats.in.ZarrReader()
reader.setId(uri)
println reader
```

leads to:

```
java.lang.NoClassDefFoundError: com/bc/zarr/JZarrException
```
