🌐 Added pt-BR translations (TryGhost#21612)

no ref

Suggestion to update the translation for 'A label for the thumbs-up response in member feedback at the bottom of emails' to 'I like it' and 'I don't like it,' as this phrasing sounds better and is more appropriate in Brazilian Portuguese. Thank you.
