ExcludeIf validator should also accept booleans and closures as inputs.

According to the documentation of Laravel https://laravel.com/docs/12.x/validation#rule-exclude-if:

If complex conditional exclusion logic is required, you may utilize the Rule::excludeIf method. This method accepts a boolean or a closure. When given a closure, the closure should return true or false to indicate if the field under validation should be excluded.

This behavior is not replicated, and it would allow for more complex validation logic: here is an example on how it would be nice to use it:

class PropertyWallFinishingUpdateBody extends Body
{
    public function __construct(
        public ?array $selectedOptions,

        #[ExcludeIf(function ($value) {
            return !in_array('OTHER', $this->selectedOptions);
        })]
        public ?string $material_other,
    ) {}
}
