Creating a list of language names in the local language

Update: use [`@olizilla/lol`](https://github.com/olizilla/lol)

---

Transifex has an api that'll let you get info about the languages it supports

https://docs.transifex.com/api/language-info

```console
$ curl -i -L --user api: -X GET https://www.transifex.com/api/2/language/pt_BR/

{
"rtl": false,
"pluralequation": "language.pluralequation",
"code": "pt_BR",
"name": "Portuguese (Brazil)",
"nplurals": 2
}
```

but it gives you the locale in POSIX format, and the languge name in english.

It'd be optimal to only include language names that we currently have translations for, rather than all possible language names, so we could write a script to list the locales directory (in the case of webui) and output a json file with the browser locale and the local language name. I'm stugglin to find a module that supports all the local language names including region modifiers. https://www.npmjs.com/package/langs looks good, but no modifiers.

https://github.com/nohamelin/simple-locale-switcher/wiki/Language-Names-for-Locale-Codes is a nice list, but incomplete. and so on.

Start by reviewing the proposed @olizilla/lol package and the Transifex language-info API, then inspect the webui locales directory mentioned in the issue. The work is complete when the supported locales can produce a JSON listing of browser locale codes and their language names in the local language, including region modifiers.
