fix: fix bicycle_types files being named incorrectly

[ST-DDT]

Fixes #471

I decided to rename the files to bicycle_types instead of changing the definition to bicycle, because for the other vehicles there is already the type module (which probably should be called vehicle_types or car_types instead).

This fixes a bug that was already present in 5.5.3, but blocks writing working tests for the vehicle module. See also #469.
