New translations: Brazilian Portuguese and Korean

[mgeisler]

Hi all,

Thanks to our incredible volunteer translators, the course is now translated into two languages:

Brazilian Portuguese by @rastringer and @hugojacob,
Korean by @keispace, @jiyongp, and @jooyunghan.

There are several other translations in the pipeline and you're welcome to come and help out!

The course has around 1,300 pieces of translatable text, so there is enough for everybody 😅 We use a Gettext based workflow so that we can keep things updated as the English source text changes.
