Add option for exclute test operation

[okr1m]

Could be usefull add ability to disable test operation in JsonDiff
some node classes like fast-json-patch work also without and in websocket comunication can reduce traffic with large amount of change

if ($this->jsonPatch !== null) {
    if ( ! self::SKIP_TEST_ENTRIES ) {
        $this->jsonPatch->op(new Test($this->path, $original));
    }
    $this->jsonPatch->op(new Replace($this->path, $new));
}

Good point. I added #73 to introduce a new option SKIP_TEST_OPS that skips test operations when creating the JSON patch document.

This is our current workaround—just in case anyone is interested:

$p = array_values(
    array_filter(
        $r->getPatch()->jsonSerialize(), 
        static fn(object $op) => $op->op !== \Swaggest\JsonDiff\JsonPatch\Test::OP
    )
);

Implemented in #73 and already released by @vearutop. Thanks a lot!
