Issues mapping property names

[bbuck]

edit/note: if relevant, we're still using v3 (3.10.0)

I seem to be misunderstanding what MapName and MapInputName are supposed to do:

> class SCCExample extends Spatie\LaravelData\Data {
        public function __construct(
                #[Spatie\LaravelData\MapInputName('ticket_price')]
                public string $ticketPrice,
        ){}
}
> SCCExample::from(['ticket_price' => '10'])

   Spatie\LaravelData\Exceptions\CannotCreateData  Could not create `SCCExample`: the constructor requires 1 parameters, 0 given. Parameters missing: ticketPrice.

> class SCCExample2 extends Spatie\LaravelData\Data {
        public function __construct(
                #[Spatie\LaravelData\MapName('ticket_price')]
                public string $ticketPrice,
        ){}
}
> SCCExample2::from(['ticket_price' => '10'])

   Spatie\LaravelData\Exceptions\CannotCreateData  Could not create `SCCExample2`: the constructor requires 1 parameters, 0 given. Parameters missing: ticketPrice.

It's my understanding that the MapName/MapInputName should enable me to use the aliased name (in this case ticket_price) to map to ticketPrice but it continues to fail saying the parameter is missing.
