Translate the rule sentences into Brazilian Portuguese

#261 rebuilt the Sieve rule summaries and the recurrence descriptions as whole
sentences with placeholders, so that a translator can move the parts rather
than being handed " and " on its own. This is the Brazilian Portuguese half of that.

32 strings and 9 plural forms. The ordinals are words -- there is no suffix to
append here, which was the point -- and the day and item lists are joined by
Intl.ListFormat rather than a translated separator.
