Ensure paginate updates when samples value changes in Dataset

[hannahblair]

Description

We weren't updating the paginate value in the Dataset component, so I've we dynamically populated the value of samples, the paginate bool would still be false. This PR adds reactivity logic to the paginate value.

❓ Shall I add an e2e test for Dataframe in this PR?

To test, run the following demo and click "get samples". Check the pagination works as expected in the dynamically updated Dataset.

import gradio as gr

def get_samples():

    samples = [['1'],['2'],['3'],['4'],['5'],['6'],['7'],['8'],['9'],['10']]
    return samples

with gr.Blocks() as demo:
    with gr.Row(variant='panel'):
        with gr.Column():
            ds_tbox = gr.Textbox(label='Example Name', visible=False)
            samples_ds = gr.Dataset(components=[ds_tbox], headers=['Samples'],label='Sample Questions', samples=get_samples(),samples_per_page=5)
        with gr.Column():
            examples_name_tbox = gr.Textbox(label='Examples Name', visible=False)
            examples_ds = gr.Dataset(components=[examples_name_tbox], headers=['NIL Questions'],
                                     label='Example Questions - click to select', samples='', samples_per_page=5)
    with gr.Row():
        get_examples_btn = gr.Button(value="Get Examples")
        get_examples_btn.click(fn=get_samples,inputs=None, outputs=examples_ds)

if __name__ == "__main__":
  demo.launch()

Closes: #7303

The code changes look good to me @hannahblair !

I think a test would be nice but imo this is a small bug so not sure we need a whole e2e just for this functionality.

@freddyaboulton Yeah, we don't actually have any tests in place for the Dataset right now, so I'm going to leave writing tests for this until I have the bandwidth
