describe tracktype=grade1 as paved only

This applies 2018 edit to tracktype page also here (see https://wiki.openstreetmap.org/w/index.php?title=Template:Map_Features:tracktype&diff=1627780&oldid=1448864 )

Seems to be confirmed and accepted by https://lists.openstreetmap.org/pipermail/tagging/2022-September/thread.html#65411

If that is incorrect then https://josm.openstreetmap.de/ticket/22102 and streetcomplete/StreetComplete#4105 and OSM Wiki should be modified to stop complaining about `surface=compacted tracktype=grade1`
