wrong field name in siri_vehicle_locations - schedualed should be scheduled

## reproduction steps
* open the API interface for siri_vehicle_locations/list - https://open-bus-stride-api.hasadna.org.il/docs#/siri/list__siri_vehicle_locations_list_get
* input a value for siri_rides__schedualed_start_time_from / siri_rides__schedualed_start_time_to fields
* run the query

### expected
* filter by scheduled start time from/to

### actual
* no filter because field is not spelled correctly in the schema
* when field is fixed in the query to the correct spelling it works
