Use GO zkcli instead of trash BASH one

With Debian 12+ the interactive zkCli.sh is completely broken, failing
to load the JLine module regardless of what is done, and no one in the
project seems to care about that.

Instead let's swap this out for the (non-interactive) GO-based zkcli of
https://github.com/go-zkcli/zkcli instead, as this suits our needs
nicely.
