Remove pakketautomaat text from DHL and PostNL entries

Split off from #11071.

Removes the "pakketautomaat" text from two entries, which can be seen as descriptive rather than being part of the brand. Draft for now, waiting for more community feedback

It's been 4 months - was there ever any community feedback?

I strongly support this. In fact, I would like to one day propose removal of the generic term for parcel lockers from brand names in my country, together with all the substitutions companies made up, because one company somehow manage to get the term parcel locker registered as a trademark.

The names we provide are supposed to used in maps. And in maps, as much information as possible is supposed to be conveyed through symbols. It can be expected that a map showing parcel lockers will have an icon for that POI type and so repeating the same information in text is an overkill and just adds clutter to precious map space.
