Whenever we have a new language, we start exposing it as language without the country specific code.
I'd propose to rename all this from pt-BR to pt and then split it up into pt-BR and pt-PT once someone comes up and suggest specific changes per country. Would you be fine with that? This would also allow Portuguese speakers from other countries than Brazil to automatically see a Portuguese translation.

Hi @m-mohr. Thanks for the review. I'm fine with that! No problem, let's rename it to "pt".

[m-mohr]

I left a couple of comments and we have two other to dos to onboard this:

1. Potential rename from pt-BR to pt
2. Add you to the GitHub repo. I've sent an invite.
