Fix spelling of Vienna tram 5 stop Nußdorfer Straße, use full name Nußdorfer Straße / Alserbachstraße as used by Wiener Linien in most places (and to match the other lines).

Redaction bot fix: I know those ways (Donauinsel near U2 Donaustadtbrücke), cycling is definitely allowed on them. (Can a cyclist please check all the "foot" paths on the Donauinsel?)

There is no WC/shower at this location anymore (checked both on site and against wien.gv.at).
