Based on the discussion in #6465.
It changes two things:

1. It removes the name/brand requirement for the elements that only get resurveyed. In effect this only applies to leisure = park and amenity=charging_station since the other elements are already excluded from the name filter. This does not affect any of the other places that we add opening hours for.
2. I also added these elements to the resurvey filter:

leisure ~ garden|beach_resort|sports_centre|disc_golf_course|nature_reserve|playground|fitness_station
or tourism = attraction
or amenity ~ place_of_worship|parking|research_institute|shower|grave_yard|kitchen|marketplace
or railway = station
or aeroway = terminal
or man_made = observatory

Thus we only ask for them if they already have (potentially out of date) opening_hours tagged.
These all seem like places that may have opening hours but commonly but also might not have them, so surveying them for elements where opening_hours is not set seems spammy.
All of these places seem to me like places that are unlikely to be confused, so a name is not required to correctly identify them because they are either: large enough so that they can be clearly identified even with inaccurate GPS or rare enough so that they are very unlikely to be close to each other.
3. I have removed a duplicate filter: We filter for name / brand twice, once in the filter and once with the hasName function. The former allowed noname = yes while the latter does not. This gets rid of code duplication and inconsistency. Instead we only use the filter.
4. I added additional tests to verify the functionality.
