Update translation of Cs:Tag:route=hiking

After a discussion on the tagging mailinglist, I have updated the wiki page of https://wiki.openstreetmap.org/wiki/Tag:route%3Dhiking
Where it originally stated to use oneway=yes/no/cw/ccw, we changed it to signed_direction.
Could somebody speaking czech please update https://wiki.openstreetmap.org/wiki/Cs:Tag:route%3Dhiking accordingly? Thanks.

Done.

Děkuji
