[Bug]: Undefined array key "input" when streaming with files attached

[arturspon]

Description

This bug started happening after #406.

When sending a message with a file and using streaming, it raises an exception with the following message: "Undefined array key "input".

Modifying the line 48 of the file src/Responses/Threads/Runs/Steps/Delta/ThreadRunStepDeltaObject.php to $attributes['input'] ?? '' made it work.

Stacktrace:

ErrorException: Undefined array key "input"

Steps To Reproduce

1) Create an assistant; 2) Create a thread; 3) Create a message in the thread and stream the response, like below:

OpenAI::threads()->messages()->create($chat->thread_id, [
    'role' => 'user',
    'content' => 'analyze this file and provide an overview for me',
    'file_ids' => {your_file_ids},
]);

$stream = OpenAI::threads()->runs()->createStreamed(
    threadId: {your_thread_id},
    parameters: [
         'assistant_id' => {your_assistant_id},
    ],
)

foreach ($stream as $chunk) {
    // code
}
