fix(jsonify): fix array jsonify handler

[Emiyaaaaa]

hey！this is my first contribution

1. fix Jsonify: readonly messes with Jsonified tuple types #629
2. fix another jsonfity array bug

// main branch
declare const mixTupleJson: Jsonify<['1', typeof fn, 2]>; // type: ['1', 2]
// this pr
declare const mixTupleJson: Jsonify<['1', typeof fn, 2]>; // type: ['1', null, 2]

// because `FilterNonNever` filter all NotJsonable value. but in array, NotJsonable value should be `null`

fix another jsonfity array bug

Would you be able to split this out into a separate pull request? That would make it easier to review.

fix another jsonfity array bug

Would you be able to split this out into a separate pull request? That would make it easier to review.

1. fix Jsonify: readonly messes with Jsonified tuple types #629 bug just make array and readonly array use same handler.
2. but previous array handler JsonifyList is wrong, this handler filter all NotJsonable value, that will make JsonifyList<Array<number>> type to never[] but not null[], it's obviously not right.
3. but, how previous jsonify array test passed ?
   https://github.com/sindresorhus/type-fest/blob/main/source/jsonify.d.ts#L119C1-L119C1 this line is wrong, not all array match this rule T extends [unknown, ...unknown[]] like Jsonify<Array<number>>, thay match next rule T extends ReadonlyArray<infer U>, this handler just right for Array<...>, wrong for readonly [1,2,3]

so i fixed JsonifyList type, and i think this is another bug. maybe my thoughts is wrong and i fell split this is a little difficult

sorry about that
