Enhance reanalysis-forced notebook

[navidcy]

Let's enhance the notebook reanalysis-forced at https://regional-mom6.readthedocs.io/en/latest/demo_notebooks/reanalysis-forced.html with some plots of, e.g, the domain or the initial condition etc.

Also let's add a thumbnail to appear at https://regional-mom6.readthedocs.io/en/latest/demos.html

Maybe moving discussion from #99 here: I've implemented a way to run the notebooks in the container on GitHub (where the model, tools, and input data are available), and provide that notebook to RTD. Example build is https://regional-mom6.readthedocs.io/en/angus-g-render-notebooks/demo_notebooks/reanalysis-forced.html, from the angus-g/render-notebooks branch.

At the moment, there's both the GitHub push webhook, and the RTDS action webhook firing for the same version, so it's not perfectly integrated until we completely switch over. There might be a little bit more to do in generating previews for PRs (for this demo, I had to manually activate the branch on RTD).

This looks great!

thumbnail still missing

Probably need to push a version of that notebook with a plot somewhere for it to show up, or specify a thumbnail file...

Yes. Related to this issue is #119 which if resolved then we could have the notebook cells evaluated locally and push.
