IGremlinQueryBase.Debug() renders CosmosDbKey as String[] insead of values

[utillity]

Describe the bug
The string produced by .Debug() is super now, allowing the developer to directly copy/paste the query to the database tool for further debugging. Currently, only the CosmosDbKey is not serialized to string correctly. Instead of showing the actual value, it is serialized as System.String[]

ie: g.V(System.String[]).hasLabel('Article')\n.property(single,'IndexPending',true)\n.property(single,'Timestamp',638493747170715656)\n.property(single,'Trend',0)

Expected behavior
It would be great to see the actual key, as in g.V(['id', 'key']).hasLabel('Article')\n.property(single,'IndexPending',true)\n.property(single,'Timestamp',638493747170715656)\n.property(single,'Trend',0)

Version information
Using v12.6.0

Minimal working example
If you really need this, I would be happy to provide you with some code
