Speeding up the docs build

@GeorgeR227, now that we have the overhaul in #231, what is the plan for the literate examples? Are there any that need to be worked into the current docs build?

One benefit of using Literate is that we can accelerate the docs with slurm, by launching jobs for each literate page and then including them in the final docs.

Another option is to have a script that runs simulations to generate the figures and then write docs pages that include those figures as references. Then the docs pages don't have to run the code that generates the figures in the docs build. That would let us use a standard pipeline for building the docs on github actions, but a buildkite job that can launch a slurm job for each page to build the figures by simulation on hipergator.
