fixed missing keybinding: Inverter PO-750A Cover, UP/DOWN

[D5098]

There is no binding action for the cockpit item "Inverter PO-750A Cover, UP/DOWN"

It was requested among other things, and it's being implemented in ED internal build. I can't promise the new keybindings will be part of the next update though.

Thanks for clarifying.

Added in today's update.
