Description

This fixes Street Snapping when editing shapes in the GTFS editor.

When I tried it with a local Graphhopper instance before, I got the error message "bad request: profile parameter required" from the routing request.

At some point, Graphhopper switched from a vehicle parameter to profile, see https://github.com/graphhopper/graphhopper/pull/1934 and https://github.com/graphhopper/graphhopper/blob/master/CHANGELOG.md#70-14-mar-2023

There is already a PR https://github.com/ibi-group/datatools-ui/pull/948 for updating this code, but it has not been edited since over two years. This edit aims to be minimally invasive to restore the routing functionality.
