[10.x] Allow to pass Arrayable to whereIn and whereNotIn queries

[Joel-Jensen]

One annoyance that we often have and where the ecosystem doesn't feel cohesive throughout, is when adding search to an existing query and it suddenly stops working because of a collection being passed to whereInor whereNotIn.

$users = collect([1]);

Existing query without Scout

User::whereIn("id", $users)->get(); 
// Returns 1 user

Adding Scout...

Before change

User::search("Taylor")->whereIn("id", $users)->get(); 
// TypeError  Laravel\Scout\Builder::whereIn(): Argument #2 ($values) must be of type array, Illuminate\Support\Collection given

After change

User::search("Taylor")->whereIn("id", $users)->get(); 
// Returns 1 user

I don't like that I had to remove a type declaration, but by looking at other classes (1, 2) this seems to be the way to go.
