Deephaven express: Not using WebGL for line plots

[mofojed]

Description

If you create a line plot in plotly express, it seems to just use the canvas instead of the WebGL optimized canvas. We should be using WebGL to render when it is enabled. With legacy plots it does use WebGL.

Steps to reproduce

1. Run the following:

from deephaven.plot import express as dx
from deephaven.plot.figure import Figure

_stocks = dx.data.stocks()

p = dx.line(_stocks, "Timestamp", "Random")
p_legacy = Figure().plot_xy(series_name="Plot", t=_stocks, x="Timestamp", y="Random").show()

2. Check the plot p_legacy Chart component props data type
3. From the React DevTools, check the plot p Chart component props data type

Expected results
2. Plot type should be scattergl
3. Plot type should be scattergl

Actual results
2. Plot type is scattergl for the legacy plot
3. Plot type is just scatter for the express plot

Seems p_scatter = dx.scatter(_stocks, "Timestamp", "Random") does render with scattergl, perhaps we only disabled this on line plots when downsampling is enabled?
