FIx java bindings packaging (#5008)

Seems to work
[here](https://github.com/vortex-data/vortex/actions/runs/18659973729/job/53197925411).
My general thinking is that `setup-protoc` runs on the provided
`container` config that's required only for the JNI build. That image
lacks unzip, so we just install it.
