Unique Rule - where parameter closure

[MarkusJLechner]

✏️ Describe the bug
See spatie/laravel-data/src/Attributes/Validation/Unique.php
https://github.com/spatie/laravel-data/blob/main/src/Attributes/Validation/Unique.php#L23

Attribute does not allow Closures, how to use that parameter?
Laravel's $rule->where allows whereIn array, which would at least work

↪️ To Reproduce
Using Unique Attribute with where closure.

✅ Expected behavior
Where should be at least usable as array

🖥️ Versions

Laravel: 12
Laravel Data: 4.17
PHP: 8.3

They will be supported in PHP 8.5, another PR is in the making #1085 that would also allow these stay tuned for more.
