Pull request overview

Updates the bundled Plotly.js dependency to v3.7.0 and refreshes the associated generated artifacts (schema, graph object docs, and JS build outputs) so plotly.py stays aligned with upstream Plotly.js behavior and configuration options.

Changes:

• Bump Plotly.js from 3.6.0 to 3.7.0 across Python and JS metadata, including the lockfile.
• Refresh generated schema / graph object documentation and related config descriptions (notably the “send to cloud” modebar button naming).
• Update updateplotlyjs workflow to rebuild JS bundles and include updated JupyterLab extension artifacts.
