Import "Closure" in CrudFilter for a proper auto-complete

[justRau]

use Closure; is missing from imports, resulting in Closure used in docblocks being treated as Backpack\CRUD\app\Library\CrudPanel\Closure and therefore IDE auto-complete and static code analysis fails, when using something like this

$this->crud
    ->filter('created_at')
    ->label('Created at')
    ->type('date_range')
    ->logic(function (string $values) {
        $values = json_decode($values, JSON_OBJECT_AS_ARRAY);
        $from = $values['from'];
        $to = Carbon::parse($values['to'])->addDay()->toDateString();

        $this->crud->addClause('whereBetween', 'created_at', [$from, $to]);
    });

in CRUD controllers.

BOOM! Your first PR with us, thank you so much! Someone will take a look at it shortly.

Please keep in mind that:

• if this constitutes a breaking change, it might take quite a while for this to get merged; we try to emulate the Laravel release cycle as much as possible, so developers can upgrade both software once; this means a new big release every ~6 months;
• even if it's a non-breaking change, it might take a few days/weeks for the PR to get merged; unless it's a no-brainer, we like to have some community feedback on new features, before we merge them; this leads to higher-quality code, in the end; we learnt this the hard way :-)
• not all PRs get merged; sometimes we just have to hold out new features, to keep the packages lean; sometimes we don't include features that only apply to niche use cases;
• we're not perfect; if you think we're wrong, call us out on it; but in a kind way :-) we all make mistakes, best we learn from them and build better software together;

Thank you!
