Issues with the $callback parameter type in the last and first methods

[dragomano]

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

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

PHP 8.4.1

Possible solution: callable $callback = null => ?callable $callback = null
