chore(build): Install Workbench CLI via conda (#3410)

I got connectome-workbench onto conda-forge:
https://github.com/conda-forge/connectome-workbench-split-feedstock

It has a connectome-workbench-cli package that excludes the GUI, and now
this is one fewer things to have special in the Dockerfile.
