Enhancement: Use python installed plotly.min.js instead of renderer.

Adding fig.update_layout(legend_groupclick="toggleitem") (as documented) to the grouped legend items example does not affect legend click behavior in VS Code. It does when opening the figure in a browser. This appears to be because VS Code Jupyter ships with an outdated version of plotly.js.

import plotly.graph_objects as go


fig = go.Figure()

fig.add_trace(
    go.Scatter(
        x=[1, 2, 3],
        y=[2, 1, 3],
        legendgroup="group",  # this can be any string, not just "group"
        legendgrouptitle_text="First Group Title",
        name="first legend group",
        mode="markers",
        marker=dict(color="Crimson", size=10),
    )
)

fig.add_trace(
    go.Scatter(
        x=[1, 2, 3],
        y=[2, 2, 2],
        legendgroup="group",
        name="first legend group - average",
        mode="lines",
        line=dict(color="Crimson"),
    )
)

fig.add_trace(
    go.Scatter(
        x=[1, 2, 3],
        y=[4, 9, 2],
        legendgroup="group2",
        legendgrouptitle_text="Second Group Title",
        name="second legend group",
        mode="markers",
        marker=dict(color="MediumPurple", size=10),
    )

        y=[5, 5, 5],
        legendgroup="group2",

# No effect from this line

This is because the updated vscode-notebook-renderer extension has not made it to a release yet, see https://github.com/microsoft/vscode-notebook-renderers/issues/102

Would be nice if the renderer could be released with a similar cadence than the Jupyter extension and integrating the latest dependencies like Plotly.

Don’s PR should have fixed the immediate issue. The longer term idea of just using the installed plotly.min.js can be tracked as an enhancement I think.
