Corrections and new language

Correction: I was not carrying the translation skills correctly.

New language: Added language Portuguese (Brazil)

Note: I did not know if I could add my name as a "contributor", but I would like to be part of your team.

Hugs! :)

I added improvements in the Portuguese (Brazil) translation and another correction.

I just added some considerations about the translation into Brazilian Portuguese.

It depends on small adjustments but the translation looks good!
