refactor: code to pass ruff check

-   Modify `pyproject.toml` to exclude `plotly/graph_objs` from checking for now.
-   Modify `pyproject.toml` to include `anywidget` in core dependencies
    (because `plotly/basewidget.py` needs it).
-   Clean up several hundred complaints from `ruff` about unused variables and imports.
-   Clean up cases in `tests/**/*.py` where the same function name was used for several tests
    (which meant that only the last one defined was actually run).
-   Reformat code after recent changes.

 ### Generating the JavaScript Bundles for Jupyter
 
-To test `go.FigureWidget` locally, you'll need to generate the JavaScript bundle as follows:
-
-```
-cd js
-npm install && npm run build
-```
-
 If you make changes to any files in the `js/` directory,
 you must run `npm install && npm run build` in the `js/` directory to rebuild the FigureWidget and JupyterLab extension.
 You must then commit the build artifacts produced in `plotly/labextension`.
