LightDescription missing hardware_number for VisualPinball.Engine platform

[jsm174]

While working on dependency updates for VisualPinball.Engine.Mpf, we noticed an exception while parsing lights when a user presses Get Machine Description.

Coils and switches currently have a number node. Lights seem to be missing a number node:

Other examples in the repo reference number for lights as well:

Hello again. We are about to release a new version of VisualPinball.Engine.Mpf. @jabdoa2 - Any thoughts on this issue?
