Automatically change operator to IN for array values

[amostajo]

Current, in order to use arrays, it has to manually change the operator to:

$builder->where( [
    'ID' => [
        'operator' => 'IN',
        'value' => $array_value,
    ]
] )

Change it so it array is automatically detected, and the operator is set as IN when this happens:

$builder->where( [
    'ID' => $array_value,
] )

From a, strictly speaking, explicit standpoint, it's made really clear what is happening, but I can see why a fix like this is nice.
