Issue with parameter type of Humanoid.Seated signal

[Felyrun]

There is an issue with a parameter type of the Humanoid.Seated Signal.
The currentSeatPart parameter is marked as type Seat | VehicleSeat even so it could also be of type undefined if the active
parameter is false.

If the character is sitting down, the active parameter will be true and currentSeatPart will be the seat they are currently sitting in.
If the character got up from a seat, the active parameter will be false and currentSeatPart will be nil.
