[9.x] Modify DatabaseRule to accept Arrayable instance inside where methods

[amaelftah]

Resubmission of #39620 cause it's a breaking change

i found that when using the Rule::where or any where methods they only accept arrays ... while the underlying query builder can accept collections too ... so I have modified the implementation and here is an example of before vs after

before

$names = collect(['foo', 'bar']);
$companiesIds = collect([1, 2]);

$request->validate([
    'first_name' => Rule::in($names),
    
     //here we have to chain ->toArray()
    'company' => Rule::exists('companies','id')->wereIn('id', $companiesIds->toArray()); 
]);

after

$names = collect(['foo', 'bar']);
$companiesIds = collect([1, 2]);

$request->validate([
    'first_name' => Rule::in($names),
    'company' => Rule::exists('companies', 'id')->wereIn('id', $companiesIds); //no need to chain ->toArray()
]);

i didn't write tests for that behavior cause i felt i will have to repeat some methods inside or use data providers ValidationExistsRuleTest ... and also the query builder behavior is already been tested ... so if it's ok to duplicate am ok to write them
