Consolidate route options tests

[LukasPaczos]

We currently have https://github.com/mapbox/mapbox-java/blob/main/services-directions/src/test/resources/route_options_v5.json and https://github.com/mapbox/mapbox-java/blob/main/services-directions-models/src/test/resources/route_options_v5.json

which are identical and need to be maintained at the same time to run tests in 2 different modules. We need to consolidate the files to make maintenance easier.
