New array validation rule required_array_keys

Laravel 8.82 adds a required_array_keys validation rule. The rule checks that all of the specified keys exist in an array.

Valid data that would pass the validation:

 1$data = [
 2    'baz' => [
 3        'foo' => 'bar',
 4        'fee' => 'faa',
 5        'laa' => 'lee'
 6    ],
 7];

 9$rules = [
10    'baz' => [
11        'array',
12        'required_array_keys:foo,fee,laa',
13    ],
14];
15 
16$validator = Validator::make($data, $rules);
17$validator->passes(); // true

Invalid data that would fail the validation:

 1$data = [
 2    'baz' => [
 3        'foo' => 'bar',
 4        'fee' => 'faa',
 5    ],
 6];
 7 
 8$rules = [
 9    'baz' => [
10        'array',
11        'required_array_keys:foo,fee,laa',
12    ],
13];
14 
15$validator = Validator::make($data, $rules);
16$validator->passes(); // false
