chore: rebuild JS widget bundles and lab extension with rangeslider fix

[shadow-byte-warrior]

Link to issue

Closes #5614

Description of change

Rebuilds the compiled plotly.js assets and Jupyter extension widgets within plotly.py to pick up the upstream rangeslider fix for rangemode: "fixed". This addresses the initial rendering bug where unexpected thick gray horizontal bars would span the slider track when the plot initially loads.

Demo

Initial rendering (Before upstream fix/bundle rebuild):
The rangeslider displays two thick, solid gray bars stretching across the track width.

After upstream fix/bundle rebuild (Expected):
The range slider track displays cleanly with the correct default visual background.

Testing strategy

Verified using the reproduction script locally. Python tests in tests/test_core/test_graph_objs/ were run and passed successfully to ensure no regressions were introduced to the figure schemas or serialization.

Additional information

This is a package dependency integration PR aligning plotly.py package assets with the upstream resolution of the rangeslider layout rendering initialization bug in plotly.js.
