Fix bug multiple bokeh plots

[freddyaboulton]

Description

Closes: #3881

Issue was that the same div was edited across multiple plots. Using unique div ids fixes the problem.

To test, run repro in issue

import gradio as gr
from bokeh.plotting import figure

with gr.Blocks() as demo:
    x = list(range(11))
    y0 = x
    y1 = [10 - i for i in x]

    p1 = gr.Plot(label='Plot 1')
    b1 = gr.Button('B1')
    p2 = gr.Plot(label='Plot 2')
    b2 = gr.Button('B2')

    def plot1():
        fig = figure(width=250, height=250, title='Plot1')
        fig.circle(x, y0, size=10, color="navy", alpha=0.5)
        return fig

    def plot2():
        fig = figure(width=250, height=250, title='Plot2')
        fig.triangle(x, y1, size=10, color="firebrick", alpha=0.5)
        return fig

    b1.click(plot1, outputs=p1)
    b2.click(plot2, outputs=p2)

    demo.launch()

A note about the CHANGELOG

Hello 👋 and thank you for contributing to Gradio!

All pull requests must update the change log located in CHANGELOG.md, unless the pull request is labeled with the "no-changelog-update" label.

Please add a brief summary of the change to the Upcoming Release > Full Changelog section of the CHANGELOG.md file and include
a link to the PR (formatted in markdown) and a link to your github profile (if you like). For example, "* Added a cool new feature by [@myusername](link-to-your-github-profile) in [PR 11111](https://github.com/gradio-app/gradio/pull/11111)".

If you would like to elaborate on your change further, feel free to include a longer explanation in the other sections.
If you would like an image/gif/video showcasing your feature, it may be best to edit the CHANGELOG file using the
GitHub web UI since that lets you upload files directly via drag-and-drop.
