close #262 by using react-snap to prerender pages

[hamirmahal]

This pull request attempts to close #262.

At the time of this writing, it adds minimal CSS needed for the page to render by adding

"reactSnap": {
    "inlineCss": true
},

to package.json, adds the react-snap dependency and postbuild script for it in package.json, and updates src/index.js to attach event listeners to already created HTML if react-snap already pre-rendered HTML contents or rendered them on the server.

This is the message that occurs on the failed run that's not Vercel.

I researched it a bit and the owner of react-snap says "This is not an error of minimalcss. This is an issue in react-snap (there is no try-catch around minimalcss https://github.com/stereobooster/react-snap/pull/263/files#diff-168726dbe96b3ce427e7fedce31bb0bcR261). Nothing to fix in minimalcss" on an issue page open in minimalcss for the same error message we received.

A more recent issue with the same error message says, "Disabling the website's service worker works!"

Is that something we want to do?
