Vehicle accessibility_attributes type inconsistency

[johnzuk]

Describe the bug
Vehicle accessibility_attributes is inconsistent between different modes

To Reproduce
accessibility_attributes is Enum[] in all modes except delivery-robots where it is an object with bool only attributes

Expected behavior
accessibility_attributes should be consistent between all modes as a Enum[]

Instead of:

The accessibility_attributes object may have the following key value pairs:

• audio_cue (boolean, Optional): is the device equipped with audio cues upon delivery
• visual_cue (boolean, Optional): is the device equipped with visual cues upon delivery
• remote_open (boolean, Optional): can the device door be remotely opened to retrieve cargo upon delivery

It should be:

Accessibility Attributes

This accessibility_attributes enum represents the accessibility attributes available on a given vehicle, or the accessibility attributes utilized for a given trip.

accessibility_attributes	Description
audio_cue	is the device equipped with audio cues upon delivery
visual_cue	is the device equipped with visual cues upon delivery
remote_open	can the device door be remotely opened to retrieve cargo upon delivery

Agree thanks for seeing this. We can work to fix it in MDS 2.1.
