Issue:
bug: get_minutes returns precise-zero-minutes during fallback text matching case 
**Pre-filing checks**

- [x] I have searched for open issues that report the same problem
- [x] I have checked that the bug affects the latest version of the library

**The URL of the recipe(s) that are not being scraped correctly**

- https://panelinha.com.br/receita/arroz-sirio-com-frango

**The results you expect to see**

The `total_time` should _probably_ be returned as `None` -- the recipe describes it as "Pá-Pum" ('quickly'), however that's not the same as zero-time-at-all, and so it could be misleading to return zero.  I don't think we should attempt to estmate the duration, so `None` seems like the next-best alternative at the moment.

**The results (including any Python error messages) that you are seeing**

`total_time` returns zero for the text "Pá-Pum" in the recipe timing information (credit to @jknndy for discovering and [reporting that](https://github.com/hhursev/recipe-scrapers/pull/905/files#r1366177652) during #905).
