fix: Type issue for non-default DeviceCommandHandlers

[AmineI]

There is a type issue with deviceCommand() callback's type, impacting the usage of smartApp.deviceCommand() in TypeScript.

deviceCommand() defines a callback with a command parameter of type DeviceCommand. This is incorrect, as DeviceCommand has a component attribute, instead of componentId attribute as obtained from the APIs.

Default deviceCommandHandler() is not impacted, as it uses the interface DeviceCommandsEvent, itself using the correct type DeviceCommandsEventCommand.

This is becoming a mouthful. Here are the current classes :

Incorrect for deviceCommand()

Correct for deviceCommand()

Lines 192 to 197 in 3725c0f

	export class DeviceCommandsEventCommand {
	componentId: string
	capability: string
	command: string
	arguments: any[]
	}

Note that this PR is marked as incomplete, as this DeviceCommandsEventCommand is difficult to import for external projects. I would leave that decision to you in order to export or create an interface.
