Add pt_BR translators to contributors

These people (and others who are already here) helped in the translation effort

In the first month of work we translated almost 45% of the books and articles.

Our project website (pt_BR): https://doc.fug.com.br

Our project at Zanata: https://translate.zanata.org/project/view/FreeBSD
