Include `allowed_types` in pt-BR translation

Before this commit, the `pt-BR` translation file was not including the `allowed_types` array inside the `content_type_whitelist_error` error message.
By including the `allowed_types` in the error message we give better feedback to the user - i.e. the user will know just by looking at the error message which type of files they can upload.
