We need another Portuguese speaking person to reviewing it. (Two-man rule)

Hi @froschdesign, I'm also Portuguese and I reviewed @rolandoisidoro translation. It seems good to merge to me!

Sorry for the late reply.

There seem to be an issue with wrong translation keys used across all languages. This work probably have some of them too since you most likely used english provider as a source.
A work to get all the keys validated is quite time consuming which I lack at the moment.
As such I cannot proceed with merging and releasing this PR.

If someone can undertake the work to validate the keys in english provider and then implement tests to ensure there is no key mismatch between different languages, I will gladly review the work and make sure it is accepted promptly. At which point I will be able to accept this PR as well.
