Pre-emptively include many system dependencies in publish.yml

[NeuroShepherd]

I think there should be a way to use renv, RSPM, and one of the R GitHub Actions to install all of the needed system dependencies, but, if not, can just throw something in like this to take care of probably 80% plus of system dep problems we'll run into:

- name: Install misc. system dependencies
        run: |
          sudo apt-get update
          sudo apt-get install \
            libcurl4-openssl-dev \
            libfontconfig1-dev \
            libssl-dev \
            libxml2-dev \
            libpng-dev \
            libjpeg-dev \
            libtiff-dev \
            libcairo2-dev \
            libxt-dev \
            libfreetype6-dev \
            libharfbuzz-dev \
            libfribidi-dev \
            zlib1g-dev \
            libv8-dev \
            libglpk-dev \
            librsvg2-bin

The setup-r-dependencies workflow uses pak, and:

pak automatically install the system dependencies of all installed R packages on the following Linux Distributions

However, many R packages need the system dependencies to be installed first in order to be installed themselves so this approach doesn't work.

Consider using this caching of apt packages action:
