Fix generate() call in object_detection.ipynb to follow the latest parameter order

[JoeJoe1313]

What?

The generate() call in examples/object_detection.ipynb was following an older version of the package, and the parameter order was model, processor, image, prompt, ...

output = generate(
    model,
    processor,
    image,
    prompt,
    max_tokens=1000,
    temperature=0.7
)

producing the following error

TypeError: TextEncodeInput must be Union[TextInputSequence, Tuple[InputSequence, InputSequence]]

In the latest package version prompt and image are swapped and the order should be model, processor, prompt, image ....

Changes Done

Fixed parameter order in the generate() call for Qwen2-VL

output = generate(
    model,
    processor,
    prompt,
    image,
    max_tokens=1000,
    temperature=0.7
)

and fixed parameter order in the generate() call for Paligemma

output = generate(
    model,
    processor,
    prompt,
    image,
)

Tests Done

Executed the notebook examples/object_detection.ipynb without any errors as can be seen in the PR.

Thanks a lot @JoeJoe1313!

I'll merge as soon as the tests pass.
