Language tabs should be URL-aware

[mattwynne]

I want to link someone to the Ruby version of https://cucumber.io/docs/cucumber/state/ but the URL doesn't change when I switch language tabs.

I'd like the language tabs to:

1. Switch to the appropriate language tab on opening a page if a querystring parameter is present (e.g. ?lang=ruby)
2. Update the URL if the language tab is changed (could be dynamic or by just hyperlinking to the new URL)

How would we achieve this?

I think the code for the tabs is here: https://github.com/cucumber/docs/blob/main/themes/cucumber-sb/static/js/site.js
