X Title: Widen return type of pyplot.subplot_tool to object | None by karlhillx · Pull Request #31997 · matplotlib/matplotlib

Description: Widen the return annotation of pyplot.subplot_tool and NavigationToolbar2.configure_subplots from SubplotTool | None to object | None. The Qt backends return a QDialog and the toolmanager branch already returns None, so the annotations were misleading. Direction per timhoffm on #31979. Docstring updated to describe the backend-dependent return value. Also drop the now-unused TYPE_CHECKING import of SubplotTool, and alphabetize the typing import. Closes #31979
