#[GreaterThan], #[GreaterThanOrEqualTo], #[LessThan], #[LessThanOrEqualTo] works not as expected (size comparision)

✏️ Describe the bug
Usage of the validation Attributes

• #[GreaterThan]
• #[GreaterThanOrEqualTo]
• #[LessThan]
• #[LessThanOrEqualTo]

is not fully compatible with the laravel implemetation of the corresponding validation rules. While the laravel documentation allows a field or a comparison value to be passed, the implementation in laravel-data always tries to evaluate the given value as a field reference.

https://laravel.com/docs/11.x/validation#rule-gt
The field under validation must be greater than the given field or value. The two fields must be of the same type. Strings, numerics, arrays, and files are evaluated using the same conventions as the size rule.

The constructor method of those validation rules looks like:

// Spatie\LaravelData\Attributes\Validation\LessThan
public function __construct(
        string|FieldReference $field,
    ) {
        $this->field = $this->parseFieldReference($field);
    }

✅ Expected behavior
When a string is passed to the constructor it is evaluated as a comparision value instead of a field reference.
