Update Portuguese README to match English

[auremoser]

Context

We're trying to better localize our Study Groups introduction README for different languages.

Description

We recently updated our README in english, and changed much of the language associated with how to get started with Study Groups. We previously had a lovely translation in [Portuguese for the README]() but have not yet updated it to match the changes in English. Please help if you can!

Steps

• Look at the english README
• Fork this Study Groups Repo
• In Terminal:
  • clone [ssh key for Study Groups fork]
  • cd [path to studyGroup repo on your local computer]
• Open the README and the README-pt.md in a text editor
• Translate the README-pt to match the english as close as possible, save changes
• Commit changes and submit a pull request to update the Portuguese translation
  • git status
  • git commit -m "SOME COMMENT ABOUT YOUR CHANGES"
  • git push origin master
