Adapt vehicle types from openx harmonization

[thomassedlmayer]

This PR aims to adapt the vehicle type definitions and descriptions that are defined by the OpenX Traffic Participants Specification.

I also replaced the old meaningless ("Vehicle is a car") descriptions with the ones of the OpenX specification.

@yash-shah-asam Could you check if there is a permalink to the OpenX specification, I could use? I think it would be reasonable to include a permalink to the specification and somehow signify that OSI tries to adhere to these definitions.

I think there a still some issues open for discussion:

1. OSI currently defines TYPE_DELIVERY_VAN which should probably be deprecated (as it contains a role). I added the preferred alias TYPE_VAN.
   Decision from TrafficParticipant Working Group: Deprecate TYPE_DELIVERY_VAN in favor of TYPE_VAN in order to move away from describing roles.
2. OSI currently defines bicycles to not include a motor ("Vehicle is a bicycle (without motor and specific lights)") whereas the OpenX specification includes motor-assisted bicycles.
3. TYPE_MOTORBIKE contradicts the naming in the OpenX specification ("Motorcycle"). I added an alias. I'm not sure if we should deprecate TYPE_MOTORBIKE or just keep both.
   Decision from TrafficParticipant Working Group: Deprecate TYPE_MOTORBIKE, introduce TYPE_MOTORCYCLE
4. I added TYPE_MICROMOBILITY_DEVICE which includes stand-up scooters but OSI already defines the type TYPE_STANDUP_SCOOTER. Should it be deprecated? It seems like an issue that in the description of micro-mobility devices the stand-up scooter is even mentioned as an example.
   Decision from TrafficParticipant Working Group: Adapt TrafficParticipant Specification to introduce types for stand-up scooters instead of including them in the more generic category for micro-mobility devices.

Apart from these issues, the changes are relatively straightforward and don't contradict the current OSI definitions from my point of view.

Thanks for the initiative and quick implementation, @thomassedlmayer ! I would agree to deprecate DELIVERY_VAN and MOTORBIKE. Regarding the BICYCLE and what they do / don't include let's dicuss in the group again. Same for the scooter...

[jakobkaths]

The Wheelchair was sorted into Micromobility Device as well in the OpenX definition. We have to make sure that we don't keep surplus definitions here, either. But again, we could discuss in the group if this is maybe prominent enough to spearate it into a dedicated type.

[thomassedlmayer]

The discussion result was to separate out both wheelchair and stand-up scooter types from micro-mobility device in the harmonized traffic participation specification and specifically state this in the description.

I adopted the changed descriptions from here.

@jakobkaths I synced the wording/grammar changes from the traffic participant specification and put the label ReadyForCCB so this can be reviewed this in the CCB tomorrow morning. Could you also have a look again?

[jakobkaths]

Looks good in general, I only have some comments regarding the standards "brand names". Also, in our discussions we said that the UN categories etc. shouldn't really be normative, but more like a hint, but I would personally be okay with it this way as the "note" and the "roughly" indicate this.
