Install rubin-env=3 stack at Hilo and summit.

We need a new stack on the Subaru machines, built on the conda-forge rubin-env=3.0.0 specification, which is what is currently installed for the w.2022.17 LSST stack via the current pfs_pipe2d install-pfs.sh script.

At Hilo this will require additional packages for Jupyterlab, etc. Just to keep things under obvious control, I propose adding those directly to the stack with conda (or mamba) install -c conda-forge  commands, then annotating this ticket.
