Support internationalization of text inside the website

[Orta Therox (orta)]

Note the nav above: this PR allows code inside React to be translated. Adds the website section to #100

Interesting things because of this:

• Bumped node version of this project to minimum of 13, because that is when internationalization was added natively. We don't use any of those APIs yet (maybe never (like dates/number formatters etc) but better to be sure)

• I switched form "leet" to "vo". The locales are verified to be real in the i8n code, and well, "leet" isn't an ISO 639-1 code. So I found the one with only 20 language speakers in the world: Volapük

As an aside, I did some work on the code syntax coloring - it now passes the a11y audits on CI.
