Add Brazilian Portuguese translation to quizdown-js

[andersonmdcanteli]

I would like the Brazilian Portuguese translation to be added to quizdown-js.
I have translated the content of the src/Languages/en.json file, which I present below.

Suggestion for the src/Languages/pt.json file:

{
"next": "Próximo",
"previous": "Anterior",
"evaluate": "Avaliar",
"reset": "Mais uma vez!",
"hint": "Mostrar dica",
"resultsTitle": "Os resultados do seu teste",
"resultsText": "Você respondeu corretamente a {points} de {total} perguntas!",
"questionLetter": "Q"
}
