Stop rendering relations with `type=multipolygon` + `boundary=protected_area` about openstreetmap-carto

Thanks for the suggestion. However, i suggest we decline this.

For administrative boundaries we have clear consensus that type=boundary is the only acceptable relation type. And hence this is being required in #4431. But for boundary=protected_area this is not the case. Furthermore >70 percent of all boundary=protected_area relations are also tagged leisure=nature_reserve. And use of type=boundary vs. type=multipolygon on leisure=nature_reserve is about equal. Hence we are not anywhere near consensus among mappers regarding this.

This is true, but if you also add boundary in the mix, you will get ~16k for type=boundary and ~8k for type=multipolygon (https://overpass-turbo.eu/s/1z4l).
