Automatically generate thumbnail sizes

[camdendotlol]

Summary

• updates DocumentActions to calculate thumbnail URLs based on the ratio between the width and height of the canvas, ignoring any thumbnail items in the manifest
• updates the thumbnail grid styling to support images with shorter height (it was previously hardcoded to 220px)
• upgrades Storybook from 7.2 to 7.4
• replaces the deprecated @storybook/addon-styling package with the styling addon du jour @storybook/addon-styling-webpack
• sets showNavigationControl to false in OpenSeaDragon to disable trying to load unused icons
• deletes the aforementioned unused OSD icons

This PR also removes a bunch of unneeded dependencies, reducing bundle size by somewhere around 30-50%.

• Puppeteer
• Jest and a bunch of Jest-related packages/plugins
• npm was included as a dependency for some reason - removing it cut 400kB off the bundle size with no side effects
• npm-run-all, which was no longer used

Testing

fr640 and Taos are good for testing this, because fr640's canvases are tall and Taos's are wide. Both look good to me.

The thumbnails look much better, but I'm seeing some new errors in the console when I try this our on my local machine:

also, I see these errors when looking at an individual page:

Those errors have been in my console for a while, long before this PR. It looks like it's connected to our use of the prefixUrl option in OpenSeaDragon, which tells it where to fetch some UI images. The images are currently in the repo, but it doesn't look like we're actually using them. I'll go ahead and delete them and add the line suggested in https://github.com/openseadragon/openseadragon/issues/210#issuecomment-23445225. It removes the 404 errors and doesn't cause any noticeable UI changes.

This seems to have been a bug with Storybook and its @storybook/addon-styling plugin. We just upgraded both a month ago, but in the past month Storybook has gone from 7.2 to 7.4 and the styling plugin has been deprecated and replaced. The issue seems to be fixed after upgrading Storybook and replacing the styling plugin with the new recommended one.

Side question: Do we use Puppeteer? I notice it's in the package.json - it's a pretty hefty dependency so I'd like to remove it if we're not using it.

Thanks! Go ahead and remove puppeteer, we aren't using it since Storybook got in the mix.
