PHP 8.4 Deprecated Warning: Nullable Parameter

[satopian]

Thank you for this great library.

In PHP 8.4, I encountered the following warnings.

PHP Deprecated: eftec\bladeone\BladeOne::last(): Implicitly marking parameter $callback as nullable is deprecated, the explicit nullable type must be used instead in C:\foo\bar\lib\BladeOne.php on line 1101

PHP Deprecated: eftec\bladeone\BladeOne::first(): Implicitly marking parameter $callback as nullable is deprecated, the explicit nullable type must be used instead in C:\foo\bar\lib\BladeOne.php on line 1128

public static function last($array, ?callable $callback = null, $default = null)
Using ?callable eliminates the Deprecated warning.

The issue does not occur in v4.17.1 so I will close the issue.
Thank you.
