`ResponseInputMessageItem` has a mandatory `id` property

Describe the bug

I'm getting linter errors when using openai.responses.create() because ResponseInputMessageItem wants an id property. This property is not mentioned anywhere in the documentation, however. I guess it can be safely omitted but the type definitions should probably be updated accordingly.

To Reproduce

 const input = [
    {
      role: 'user',
      content: [
        { type: 'input_text', text: prompt },
        ...referenceImages.map((buffer) => ({
          type: 'input_image',
          detail: 'auto',
          image_url: `data:image/png;base64,${buffer.toString('base64')}`,
        })),
      ],
    },
  ];

  return openai.responses.create({
    model: 'gpt-4-vision-preview',
    input,
    stream: true,
  });
